Use of certain chemicals and radiation to change the base sequences of genes of crop plants is termed

A

recombinant DNA technology

B

transgenic mechanism

C

mutations breeding

D

gene therapy

Text Solution

Verified by Experts

The correct Answer is:
C
Mutation is the process by which genetic variations are created through changes in the base sequence within genes resulting in the creation of a new character of a new character or trait not found in the parental type. It is possible to induce mutations artificially through use of chemicals or relations (like gamma relations), and selecting and using the plants that have desirable character as a source in breeding. This process is called mutations breeding.
