Genomics is the branch of molecular biology that focuses on the structure, function, evolution, mapping, and editing of genomes. A genome is the complete set of genetic material within an organism, which includes all of its genes and DNA sequences. Genomics research involves studying the entire genome of an organism to identify genes, understand gene regulation, and discover how genetic information is inherited and expressed. Genomic research has many applications in fields such as medicine, agriculture, and evolutionary biology. It has also led to the development of technologies such as gene editing and personalized medicine.
