Important Topics of Xam Idea Class 12 Biology Solutions Chapter 12: Biotechnology And Its Applications

Some of the important concepts involved in this chapter-

What is Biotechnology?

The area of Biology, that utilizes the properties of living organisms and their components to produce useful products or technologies that can be beneficial for humans. 

Applications of Biotechnology


  • Application of Biotechnology in the Medical Field


  • The Introduction of Recombinant DNA technology in the healthcare system, that permits a mass production in the therapeutic drugs. 
  • Gene Therapy has been developed, that helps in the removal of genetic disorders in an embryo of females.
  • Humulin drugs are developed from genetic engineering, used for the treatment of diabetic patients.
  • Apart from this, the other applications of Biotechnology In the medical field are:
  • PCR


  • Application of Biotechnology in Agriculture


  • Its Application in the agricultural field is generally referred to as the Green Revolution.
  • The Application of Biotechnology in agriculture helps in food production, to generate crops, pest-resistant plants, Bt cotton plants, etc. 
  • It helps in the modification of plants, animals, microorganisms to improve its agricultural productivity.


  • Applications in Aquaculture


Biotechnology applications also help to upgrade the quality of fish. The releasing hormone gonadotropin has been injected into the fish to enhance its breeding. This helps in overall genetic characteristics, and enhances their growth, also prevents them from infectious diseases.

Transgenic Animals

  • Transgenic animals are those animals, at which a new gene has been inserted into a genome, using genetic engineering.
  • Rats, Rabbits, Pigs, Sheep, Cows, Fish are the most commonly used transgenic animals for the production of different biological products.

Production of Antibiotics

Biotechnology is also used for the production of different kinds of vaccines, antibiotics, using genetic characteristics of plants. Flucloxacillin and amoxicillin are prominent examples of it.

Exercise Discussion of Xam Idea Class 12 Biology Solutions Chapter 12. Biotechnology And Its Applications

This chapter’s questions deal with Biotechnology and its various applications and will give you a brief overview of therapeutic drugs, several techniques for removal of genetic disorders, transgenic animals, and many more. Let us consider the exercises in detail.
