Functional genomics is a field of study within molecular biology that focuses on understanding the function and interactions of genes within an organism. This area of research involves the study of gene expression, protein-protein interactions, and the regulation of gene activity to determine how genes contribute to complex biological processes. Functional genomics combines techniques from genetics, genomics, bioinformatics, and other disciplines to decipher the functions of genes and their role in various biological systems. This research is essential for understanding how genes contribute to human health, disease, and evolution.
