Genomics is an interdisciplinary field of science
focusing on genomes. A genome is a complete set of DNA within a single cell of
and as such genomics is a branch of molecular biology concerned with the
structure, function, evolution, and mapping of genomes. Experts in
genomics strive to determine complete DNA sequences and perform genetic mapping
to help understand disease. Genomics also involves the study of
intragenomic processes such as epistasis, heterosis and pleiotropy as well as the
interactions between loci and alleles within the genome.
