Numerous advances in genetics are being made today, and genomics is at the forefront of biological research. The information content of genetics is increasing at a rapid pace, as the genome sequences of many organisms are added to DNA databases every year. Genomics is the field of genetics that attempts to understand the content, organization, function, and evolution of genetic information contained in whole genomes.

The field of genomics is at the cutting edge of modern biology; information resulting from research in this field has made significant contributions to human health, agriculture, and numerous other areas. It has provided gene sequences necessary for producing medically important proteins through recombinant DNA technology, and comparisons of genome sequences from different organisms are leading to a better understanding of evolution and the history of life.
