Genomics

Definition

Genomics is the study of an organism's entire genome, which encompasses its complete set of DNA, including all of its genes and their functions. This field focuses on the structure, function, evolution, and mapping of genomes, providing insights into how genes interact with each other and the environment. Genomics plays a critical role in understanding biological processes, disease mechanisms, and the development of new medical therapies.
