Question

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

Options

• recombinant DNA technology

• transgenic mechanism

• mutation breeding

• gene therapy

• plant introduction

Answer 1

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

Explanation:

Mutation breeding is the process of exposing seeds or plant parts to chemicals or radiation (like X-rays or gamma rays) to create changes in the DNA base sequence.
These mutations may produce new traits such as higher yield, disease resistance, or improved quality in crops.
