Introduction to NCERT Class 12 Biology Chapter 12

NCERT Solutions for Class 12 Biology Chapter 12 – Biotechnology and its Applications explicitly elaborate about various biotechnology applications. Some of the topics covered in our comprehensive NCERT Solutions have been given below.

  • Introduction to biotechnology

Under this section of NCERT CBSE Class 12 Biology Chapter 12, you will get to learn about the meaning, applications and scope of biotechnology and how it is used in the development of new products for mankind. 

  • Applications of biotechnology

In this topic of CBSE NCERT Class 12 Biology Chapter 12, you will study the different applications of biotechnology for the production of useful products. This section elaborates on the mixed-use of biotechnology for the production of agriculture products, medicines, development of transgenic animals and much more. This section also tells you that biotechnology also finds use in aquaculture. 

  • Application of biotechnology in agriculture

This section of this chapter discusses in details about the various applications of biotechnology in the field of agriculture. It is also termed as green biotechnology. Here you will learn about organic agriculture, genetically engineered crop-based agriculture and agro chemical-based agriculture. 

This section further tells you that over the years, the application of biotechnology has significantly increased the yield and supported the food supply chain. Biotechnology has created pest-resistant plants and genetically modified crops to make food production sustainable and adequate for the growing population. 

  • Applications of biotechnology in medicine

In this section of CBSE NCERT Class 12 Biology Book, will get to know about different applications of biotechnology in the field of medicine. Advancements in biotechnology have given birth to recombinant DNA technology which is responsible for mass-scale production of therapeutic drugs. Genetic engineering is used to produce humulin for treating diabetes. 

This section will also tell you about how biotechnology has developed gene therapy. The gene therapy is used to remove genetic disorders in the embryo. Other applications of biotechnology in the field of medicine include PCR and ELISA.

  • Transgenic animals

Our NCERT Solutions for Class 12 Biology Chapter 12-Biotechnology and its Applications include a detailed discussion about transgenic animals and how biotechnological advancement has helped in the creation of genetically engineered genomes. From this chapter, you will get the idea about how transgenic animals are used for the production of biological products, analysis of various types of diseases, the study of genes in the development of the disease, testing the safety of vaccines and toxicity of drugs, the study of gene regulation and how it influences the normal functioning of the body.

  • Application of biotechnology in aquaculture

In this chapter, you will get to know the applications of biotechnology in improving the quantity and quality of cultured fish. Fishes are injected with gonadotropin-releasing hormones to increase breeding capabilities. 

  • Production of antibiotics

It is a significant section of this module where you learn about different methods of production of antibiotics, artificial hormones and vaccines using naturally available components. Plants are injected with engineering jeans with desired characteristics for the production of encoded proteins. Biotechnology has also helped in the production of edible vaccines that are relatively cheaper.
