Genomics

Definition

Genomics is the study of the complete set of genes and their interactions within an organism's genome. It encompasses the analysis of DNA sequences, gene function, and the regulation of gene expression, playing a crucial role in understanding biological processes. By utilizing advanced sequencing technologies and computational tools, genomics allows researchers to gain insights into complex traits, disease mechanisms, and evolutionary relationships, making it essential for various fields including personalized medicine, agriculture, and systems biology.
