Functional Genomics

Definition

Functional genomics is the field of molecular biology that focuses on understanding the function of genes and their products, particularly proteins, within the context of biological processes. This area of study utilizes high-throughput techniques and bioinformatics to analyze gene expression patterns, protein interactions, and cellular functions. By integrating genomic data with proteomic approaches, functional genomics plays a crucial role in identifying potential biomarkers for diseases, enhancing our understanding of cellular mechanisms, and facilitating personalized medicine.
