Question

answer the following question Difine Mutation ​

Answer 1

Answer:

A mutation is a change in the DNA sequence that may occur due to incorrect incorporation of nucleotide base or bases during replication or transcription or as a result of environmental factors such as UV light, radiations or mutagens. The mutation may be of different types:

Missense mutation: It is a point mutation that occurs when a change in a single nucleotide base of an amino acid occurs. This results in the substitution of one amino acid for another in the protein made by a gene.

Answer 2

The changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units In DNA, or the deletion ,insertion, or rearengment of larger sections of genes or chromosomes.
