A mutation is a change in a DNA sequence brought about either by a mistake made when the DNA is copied or through chemical damage. Regions of the genome (called genes) provide instructions for creation of protein molecules, which perform most of the important jobs in cells. Certain types of mutations are silent and have no effect, but others affect protein production in a variety of ways.
A mutation is a change in a DNA sequence introduced approximately either via a mistake made when the DNA is copied or through chemical damage. Regions of the genome (referred to as genes) provide commands for the introduction of protein molecules, which perform maximum of the important jobs in cells. Certain styles of mutations are silent and haven't any effect, but others affect protein production in a number of ways.
