FAQs on Biotechnology and its Applications in One Shot (NCERT) Video Lecture - Biology Class 12 - NEET

1. What is biotechnology and how is it applied in various fields?
Ans. Biotechnology is the use of living organisms or their components to develop or create useful products or processes. It involves the application of scientific and engineering principles to manipulate biological systems for practical purposes. Biotechnology finds applications in areas such as medicine (producing vaccines and drugs), agriculture (improving crop yield and resistance to pests), environmental conservation (remediating pollution), and industrial production (biofuels and bioplastics).
2. How is biotechnology used in medicine and healthcare?
Ans. Biotechnology plays a crucial role in medicine and healthcare by developing new drugs, therapies, and diagnostic tools. It involves the use of genetic engineering techniques to produce recombinant DNA molecules that can be used to create therapeutic proteins, such as insulin for diabetes or monoclonal antibodies for cancer treatment. Biotechnology also enables the production of vaccines, gene therapies, and personalized medicine, leading to advancements in the prevention and treatment of various diseases.
3. What are the benefits of biotechnology in agriculture?
Ans. Biotechnology has revolutionized agriculture by improving crop yield, quality, and resistance to pests, diseases, and environmental stresses. Through genetic engineering, scientists can introduce desirable traits into plants, such as drought tolerance, disease resistance, or enhanced nutritional content. Biotechnology also enables the development of genetically modified organisms (GMOs) that can produce higher yields, reduce the need for chemical pesticides, and increase food security.
4. How does biotechnology contribute to environmental conservation?
Ans. Biotechnology plays a significant role in environmental conservation by providing sustainable solutions for pollution remediation and waste management. It involves the use of microorganisms or enzymes to break down harmful pollutants, such as oil spills or toxic chemicals, into less harmful substances. Biotechnology also enables the production of biofuels, which are renewable energy sources derived from biomass, reducing the dependence on fossil fuels and mitigating climate change.
5. What are the ethical considerations associated with biotechnology?
Ans. Biotechnology raises ethical concerns regarding the manipulation of living organisms and their genetic material. These include issues related to genetically modified organisms (GMOs), such as potential environmental impacts and the labeling of GMO products. There are also concerns about the privacy and security of genetic information in fields like personalized medicine and genetic testing. Ethical considerations also arise in human cloning, stem cell research, and the patenting of life forms. It is important to have regulations and ethical guidelines in place to ensure the responsible and safe application of biotechnology.
