Summary Introduction
To analyze: The reasons for the evolution in the protein coding sequences because of the effect of the mutations.
Introduction: The sequences of proteins are diverse and are formed by the process of the translation. The mutations are present at the single positions in the amino acid sequences of the various proteins. They are caused by various processes like the gene duplication, inversion, translocation, and inversion of the loci of the genes on the chromosomes.
