Genomic studies

Genomic studies (genomics) is the study of the whole genome of an organism. Using bioinformatics and high-performance computing, genomic researchers examined massive amounts of deoxyribonucleic acid (DNA)-sequence data to discover variations or mutations that affect drug response, health, or disease. Genomics is a much younger discipline than genetics, having only emerged in the last few decades as a result of technological advancements in DNA sequencing and computational biology.
