Genomics

Definition

Genomics is the study of an organism's entire genome, which includes all of its DNA, genes, and their functions. It goes beyond traditional genetics by analyzing not just individual genes, but also the interactions between them and how these interactions affect traits, health, and disease. This field plays a crucial role in understanding biological processes and advancing healthcare and biotechnology innovations.
