Summary Introduction
To review:
The necessity of mutation for the evolutionary processes.
Introduction:
The mutation can be defined as the changes in the sequence of the genome of an organism. These are permanent alterations, which lead to the change in the sequence of genomic DNA (deoxyribonucleic acid). It can be caused by the radiations or chemicals. The mutation is basically alteration in the
