Definition of Genomics

The term genomics has been derived. from the word genome, which means the haploid (1 C) DNA content of an organism. In the past, this genome was studied in parts, one or few genes at a time, an approach which led to major progress in the field of genetics. In contrast, genomics (in its current usage) deals with the genome as a whole and had its origin in the human genome project, which involved determination of the nucleotide sequence of the whole genome; although this task was once considered impossible to achieve, it was successfully completed in April 2003, two years ahead of schedule.
Other than viruses, Haemophilus influenzaewas the first organism, whose whole genome was sequenced and published in 1995.
