FAQs on Biotechnology : Principles and Processes in One Shot (NCERT) Video Lecture - Biology Class 12 - NEET

1. What are the principles of biotechnology?
Ans. The principles of biotechnology involve the use of biological systems, organisms, or their components to develop or create new products or processes. This includes techniques such as genetic engineering, recombinant DNA technology, and cell culture.
2. What are the processes involved in biotechnology?
Ans. The processes involved in biotechnology include isolation and manipulation of DNA, gene cloning, DNA sequencing, PCR (Polymerase Chain Reaction), gene expression, protein purification, and cell culture techniques. These processes are used to study and modify genetic material for various applications.
3. How is genetic engineering used in biotechnology?
Ans. Genetic engineering is a key technique in biotechnology that involves the manipulation and modification of an organism's DNA. It allows scientists to introduce new genes into an organism or modify its existing genetic material. Genetic engineering is used to produce genetically modified organisms (GMOs), develop new medicines, improve crop yields, and enhance industrial processes.
4. What is recombinant DNA technology?
Ans. Recombinant DNA technology is a method used in biotechnology to combine DNA molecules from different sources. It involves cutting DNA fragments with restriction enzymes and joining them together using DNA ligases. This technique allows scientists to create new combinations of genes and transfer them into host organisms, leading to the production of desired proteins or traits.
5. What are the applications of biotechnology?
Ans. Biotechnology has a wide range of applications in various fields. It is used in medicine to develop new drugs, vaccines, and diagnostic tests. In agriculture, biotechnology is utilized to improve crop traits, increase yield, and develop pest-resistant varieties. It is also used in environmental applications such as bioremediation and waste treatment. Additionally, biotechnology plays a significant role in industrial processes, including the production of enzymes, biofuels, and bio-based materials.
