Functional genomics

Definition

Functional genomics is a field of genomics that aims to understand the function and regulation of genes and their products. This involves studying how genes interact with each other and with the environment to influence biological processes. By utilizing high-throughput technologies, functional genomics seeks to link gene expression patterns to phenotypic outcomes, ultimately shedding light on complex biological systems and diseases.
