Genomics is the study of genomes, the complete set of DNA in an organism, including all of its genes. It involves analyzing the structure, function, and evolution of genomes to understand how genetic variations contribute to health, disease, and development. Advances in genomics have revolutionized medicine, enabling personalized treatments and deeper insights into genetic disorders. This field combines high-throughput sequencing technologies with bioinformatics to uncover the complexities of genetic information.
