Question

What is the molecular basis of gene mutation

Answer 1

The Molecular Basis of Mutation. In gene mutation, one allele of a gene changes into a different allele. Because such a change takes place within a single gene and maps to one chromosomal locus (“point”), a gene mutation is sometimes called a point mutation.

Answer 2

Biological evolution is one of the most important biological procedures in any living organism.

Gene mutation is the most important part this biological evolution.

In the gene mutation a particular part of the DNA is permanently replaced by any another segment.

We can more specifically elaborate this gene mutation theory by it's molecular explanation.

According to the molecular basis of the gene mutation, specific nucleotides of DNA arrangement is deleted or replaced by another set of nucleotides,in order to perform the gene mutation.
