Biotechnology commonly includes a set of methods that scientists and engineers use to modify the genetic composition of organisms. Some methods, such as selective breeding, are extremely old and have been used since the beginning of agriculture.
What is the history of Biological Technology in agriculture?
Since the advent of agriculture 10 000 years ago, farmers have used biological technology inadvertently in the refinement of methods of farming and crops through cross breeding, and various hybridization techniques. Later, the genetics of plants were modified by sophisticated plant breeding programs which resulted in the ‘Green Revolution’.
What is the importance of Biotechnology in agriculture?
Biotechnology offers tremendous potential for improving crop production, animal agriculture, and bioprocessing. It can provide scientists with new ways to develop higher-yielding and more nutritious crop varieties, to improve resistance to disease, or to reduce the need for inputs of fertilizers and other expensive agricultural chemicals.
What is the earliest example of Biotechnology?
The earliest example of biotechnology is the domestication of plants and animals. Domestication began over 10,000 years ago when our ancestors started keeping plants as a reliable source of food. Rice, barley and wheat were among the first domesticated plants.
What are the applications of traditional biotechnological processes?
Traditional biotechnological processes have applications in almost all spheres of life, ranging from pharmaceuticals to food production, industrial processes, waste and wastewater treatment, bioremediation, bioleaching, biofuels, and biopolymers.

Agricultural biotechnology delivers significant and tangible benefits for farmers including increased crop yields and lower input costs. American farmers have adopted genetically engineered (GE) crops widely since their introduction in 1996, especially corn, cotton and soybean varieties.
How important is biotechnology in sustainable agriculture?
Biotechnology contributes to sustainable agriculture by reducing the dependence on agro-chemicals, particularly pesticides, through the deployment of genes conferring tolerance or resistance to biotic and abiotic stresses.
How biotechnology can be used to answer some agricultural issues?
Biotechnology is being used to address problems in all areas of agricultural production and processing. This includes plant breeding to raise and stabilize yields; to improve resistance to pests, diseases and abiotic stresses such as drought and cold; and to enhance the nutritional content of foods.
What are some examples of biotechnology?
For example, one of the most important products generated through agricultural biotechnology has been the introduction of transgenic crop plants which confer herbicide tolerance, in such a way that herbicides can be sprayed on transgenic crops without causing damage while detouring the growth of neighboring weeds.
How are public attitudes toward agricultural biotechnology influenced by the social environment?
They are largely influenced by the social environment and the mass media, particularly when the issue at stake is characterized by weak involvement and lack of direct experience. This situation applies in particular to Europe, where the de facto ban on the cultivation of GMOs in most European countries, the lack of concrete experience with labeled GM food in supermarkets and the absence of public initiatives to render a practical experience with GMOs mandatory in high school education have led to rather heteronomous views on the technology. The lack of experience with GMOs has increased the influence of stakeholders in politics in the framing of the debate. By opposing GMOs they try to assure the public of their good motives and thus gaining public trust as guardians of food safety, the environment, and social values. The situation in North America in general and the United States in particular is different since farmers, consumers, and high school students mostly have made a concrete experience with the technology and this makes it more difficult for advocacy groups to portray themselves as the voices that represent the interests of consumers and producers. In the developing world there are countries in Latin America and Asia that have embraced the technology without much public debate. However, the continent that has so far been as reluctant as Europe to embrace the technology is Africa. Apart from South Africa and a few other countries that approved of the commercial release of Bt cotton, the continent remains largely GMO free. This is however not due to genuine domestic opposition to the technology but the pressure from Europe as the largest donor to African governments and the largest importer of agricultural products from Africa.
How does biotechnology affect agriculture?
Agricultural biotechnology delivers biomass for food, feed, genetic modifications, and molecular tools to enhance the plant breeding potential, resulting in increased food supplies, farm income, and reduced damage to ecology and environment.
Why do insects die?
The insects soon die as a result of pores which are created in the gut cell membrane. The first generation of biotechnology crops focused on agronomic input traits that helped farmers; however, their value was not clear to the general consumer who is disconnected to the demands of farming.
What is genetic engineering?
The genetic engineering of crops for improved agronomic and nutritional traits has been widely reviewed in the literature. Briefly, genetic engineering involves the introduction of a novel trait into a crop through the manipulation of its genetic material.
What is agricultural biotechnology?
Agricultural Biotechnology is the use of new scientific techniques based on our understanding of DNA to improve crops and livestock that are not possible with conventional breeding alone. This can be achieved in part by modern molecular plant breeding techniques such as marker-assisted selection (MAS).
Which crops are transgenic?
The most important transgenic crop planted is soybean, followed by corn, cotton, and canola.
What are the moral critiques of biotechnology?
They are potential harm to (1) an important political-economic entity, (2) a cherished symbol if not the embodiment of basic American moral values, and (3) a solution to long-term natural resource problems. It is probably correct to say that the vast majority of the American public like family farms, support their continued existence, and, unless they have read Wendell Berry’s The Unsettling of America: Culture and Agriculture (1977), have no idea what is happening to them. Most Americans do not know that the idyllic family farms they envision, if they think of farms at all, are in deep economic trouble and are disappearing rapidly (see Halweil, 2004 ).
What is white biotechnology?
The term ‘white biotechnology’ is often used to refer to industrial biotechnology, especially in Europe. This contrasts with ‘green biotechnology’, which typically refers to agricultural biotechnology, and ‘red biotechnology’, which is commonly a synonym for pharmaceutical and medical biotechnology. In reality, there is some overlap among the three areas of the overall biotechnology field; in the case of this volume, we will discuss, for example, the utilization of large-scale cell culture and fermentation systems for the production of pharmaceutical products as well as for the production of alternative forms of energy through the bioconversion of biomass.
What is biotechnology in agriculture?
Modern agricultural biotechnology includes a range of tools that scientists employ to understand and manipulate the genetic make-up of organisms for use in the production or processing of agricultural products. Some applications of biotechnology, such as fermentation and brewing, have been used for millennia.
What is conventional breeding?
Conventional breeding, relying on the application of classic genetic principles based on the phenotype or physical characteristics of the organism concerned, has been very successful in introducing desirable traits into crop cultivars or livestock breeds from domesticated or wild relatives or mutants ( Box 3).
What is recombinant DNA?
Recombinant DNA techniques, also known as genetic engineering or (more familiarly but less accurately) genetic modification, refer to the modification of an organism’s genetic make-up using transgenesis, in which DNA from one organism or cell (the transgene) is transferred to another without sexual reproduction.
What is biotechnology?
Broadly speaking, biotechnology is any technique that uses living organisms or substances from these organisms to make or modify a product for a practical purpose (Box 2).

Modern detergents rely on enzymes produced via biotechnology, hard cheese production largely relies on rennet produced by …
How many index cards per student?
Make sure there are at least two index cards of each color per student (for a total of six index cards per student). Randomly place a star on one-fourth of the red, green, and yellow index cards. Mix all the cards together with the stars facing down. Then have each student choose two index cards of each color.
What does the new hand of cards represent?
The new hand of cards represents the genotype of the new strain of rice. Have students repeat the card exchange with other partners until someone has a hand where all the cards have stars. This represents a strain of rice that possesses all the favorable traits.
What is the impact of cloning on farming?
Impact of Cloning on Farming. Cloning is often a science fiction plot point. In the Star Wars movies, cloned humans were used as soldiers in battle. In Jurassic Park, cloned dinosaurs were used to populate a theme park.
What to do after a student has completed their research?
After they have completed their research, have each group discuss the pros and cons of the technique. Finally, tell students to imagine that a company is developing a strain of potatoes with less water content. These potatoes will be drier so that, when fried, they produce crispier French fries and potato chips.
What is media credit?

What was Louis Pasteur’s theory of fermentation?
Louis Pasteur first described the scientific basis for fermentation in the late 1800s. Pasteur’s hypothesis, called the germ theory. 6. , showed the existence of microorganisms and their effect on fermentation. Pasteur’s work gave birth to many branches of science.
What are some foods that our ancestors made?
No. Our early ancestors used microorganisms to make cheese, yoghurt and bread. They also made alcoholic drinks like beer and wine. All of these foods and drinks are made by fermentation. Fermentation. 2. is the process that many microorganisms ( yeasts, moulds and bacteria) use to convert sugars into energy.
What is fermentation used for?
Fermentation is used to create food products such as beer, wine, kombucha, bread and yoghurt. In ruminants, microbial populations ferment feed and water into volatile fatty acids and gases – methane and carbon dioxide.
What causes bread to rise?
causes bread to rise, lactic acid. 5. makes yoghurt sour, and alcohol is produced in the formation of beer and wine. Fermentation was probably discovered by accident, and our early ancestors didn’t know how it worked. Some societies thought fermentation was a miracle or gift from their god.
What is a plant that has been enhanced by selective breeding to become a better source of food?
Corn is a dramatic example of a plant that has been enhanced by selective breeding to become a better source of food. Early teosinte plants (about 5000BC) had small cobs with few kernels, but by 1500AD, the corn cobs were more than 5 times the size and packed full of sweet, juicy kernels.
What is the difference between infection and bacteria?
It has to be internally consistent, based upon evidence, tested against a wide range of phenomena and demonstrate problem solving. infection: Invasion of the body by something that could be harmful or cause a disease. bacteria: (Singular: bacterium) Single-celled microorganisms that have no nucleus.
What is honey used for?
Some traditional medicines also used organisms or parts of organisms. For example, the ancient Egyptians used honey for respiratory infections. and as an ointment for wounds. Honey is a natural antibiotic, killing the germs in wounds. By about 600BC, the Chinese were using mouldy soybean curds to treat boils.
What is co-production in science?
Co-production emphasizes the way in which the technical and social are intertwined and mutually reinforcing ; that is, science and innovation do not exist in an autonomous sphere shielded from the social context in which they occur ( Jasanoff, 2005 ). Social construction theories have spurred interest in the ways in which societal concerns, values, and diverse points of view can be incorporated into innovation pathways. Responsible innovation (RI) has emerged as a framework to meet this challenge ( Stilgoe et al. 2013; Owen et al. 2013 ). RI brings science and technological innovation into line with the democratic principles of transparency, accountability, and meaningful public input. While RI has gained traction in the European Union (EU) and UK in national policies (e.g. Macnaghten et al. 2016 ), the U.S. has yet to embrace it in research and innovation systems.
What is care in RI?
( 2013) who define RI as “taking care of the future through collective stewardship of science and innovation in the present” (p. 1570). Care constitutes a relationship between an individual and something of value whether it be another person, the environment, or a value. To care is to undertake the responsibility for the well-being of another. RI in this light is considered not a set of rules or guidelines, but rather a process through which care is undertaken ( Burget et al. 2017 ). When applied on a macro level, effective care, especially future oriented care, requires attention to a vast number of complex and intertwined social, political, environmental, and economic relationships ( Adam and Groves 2011 ).
What is homogenous focus group?
The use of homogenous focus group is part of a methodological foundation originating in the tradition of group discussion ( Morgan 1997 ), where discussion groups are taken as examples of the broader communities although they may not be statistically representative. Groups are set up to have commonalities in professional aspects related to the topics under discussion. We hosted three focus groups per sector (with the exception of 2 groups for consumer-environmental NGOs), and on a sector basis, the discussions yielded similar themes across these replicates. Therefore, although our focus groups are not meant to contain a demographically representative sample of U.S. biotechnology sectors, the themes from the discussions seem representative of the sectors.
What is academic capitalism?
Academic capitalism is the submission of universities and subsequently university scientists, to corporate, state, and individual economic interests ( Slaughter & Rhoades 2010 ). Technological innovation has long been held as a necessary condition for economic growth and international competitiveness, and economic growth has proved an enduring rationale for public spending on science. The current dominant policy paradigm has placed universities as key engines of economic growth ( Valero and VanReenen 2019 ).
How much of the public funding should be given to research in biotechnology?
There should be a standard of at least 10% of public funding for research in biotechnology that goes to environmental, social, legal, and ethical implications research. Responsiveness. The innovation process should respond to changes in public attitudes or values.
