Genomics

Definition

Genomics is the study of the complete set of DNA, including all of its genes, in an organism. It encompasses the analysis of genetic sequences, structure, function, and evolution, which allows for a comprehensive understanding of genetic influences on traits and diseases. By integrating genomic data with other types of biological information, such as proteomics, researchers can gain deeper insights into cellular functions and disease mechanisms.
