Question

How Are Mutations Important To The Process Of Evolution?

Answer 1

Mutations:

1. A mutation is a change in the structure of a gene, which is the fundamental unit of inheritance.
2. Deoxyribonucleic acid (DNA) is a long molecule made up of nucleotide bases that make up genes.
3. These nucleotide bases are Adenine (A), Thymine (T), Guanine (G) and Cytosine (C).

Role of Mutation In The Process Of Evolution:

1. The mutation is the ultimate source of all genetic variation.
2. The mutation is important as the first step in evolution because it produces a new DNA sequence for a specific gene, resulting in a new allele.
3. Intragenic recombination can also result in the creation of a new DNA sequence (a new allele) for a certain gene.
