Genomics is an area within genetics that concerns the sequencing and analysis of an organism’s genome. Genome refers to entire DNA content that is within one cell of an organism. Experts in genomics strive to determine complete DNA sequences and perform genetic mapping to help understand disease.Scientists use the term genome to refer to the complete set of DNA sequences derived from each chromosome of a given species. Genomics is a relatively new and ever-expanding field dedicated to the study of defining genomes in this more specific way.
The direct analysis of the genome of an organism, or the genomes of a group of organisms, is now possible through advances in the efficiency of DNA sequencing and large-scale genetic screening. These new high-throughput methods allow researchers to collect vast amounts of information about genetic variation in very short periods of time.
