Points to Remember
Below we have provided some of the important points to remember for NCERT notes for Class 12 Biology Chapter 11 to ace your exam:
The conventional form of biotechnology involves large-scale production and marketing of products, while the modern form involves recombinant DNA technology (rDNA) or genetic engineering involving gene manipulation.
Cloning vectors and restriction endonucleases are the key tools of rDNA technology.
Only bacteria have restriction endonucleases, which serve as a defense mechanism known as the restriction-modification system.
Electrophoresis is a technique in rDNA technology that uses an electric field to separate DNA fragments.
Bioreactors are used for the large-scale production of functional protein or rec protein.
Topics and Sub-topics
Biotechnology is the branch of Science that deals with the techniques of using biological processes or live organisms to generate products and services applicable to human beings. Biotechnology encompasses both traditional and modern biotechnology. Human beings have been using the natural capabilities of micro-organisms for thousands of years to produce valuable products.
This chapter will lend the learners an in-depth study of the principles and processes involved in biotechnology. At Vidyakul, the diagrams, illustrations, figures, and lucid language make this NCERT Class 12 Biology chapter 11 comprehensive and easy to absorb.
