COMPARATIVE GENOMICS

Comparative genomics is the analysis and comparison of genomes from different species. The purpose is to gain a better understanding of how species have evolved and to determine the function of genes and noncoding regions of the genome.It involves the use of computer programs that can line up multiple genomes and look for regions of similarity among them.So this field aims to take advantage of the information provided by the signatures of selection to understand the function and evolutionary processes that act on genomes.It studies both the proteins,RNA and regulatory regions of different organisms.One of the important goals of this field is the identification of the mechanisms of eukaryotic genome evolution.SO this field is also a fascinating one and also exciting.It is a new field of biological research.The information provided by this field helps scientists for better understanding of the structure and function of human genes and thereby develop new strategies to combat human disease.
