Genomics

Definition

Genomics is the study of the complete set of DNA (genome) in an organism, including all of its genes. This field focuses on understanding the structure, function, evolution, and mapping of genomes, which has profound implications for medicine, biology, and biotechnology. The rapid advancements in genomics are closely linked to big data and machine learning, enabling scientists to analyze massive amounts of genetic information and discover new insights about living organisms.
