The term genome was created in 1920 by Hans Winkler, [8] professor of botany at the University of Hamburg, Germany.The website Oxford Dictionaries and the Online Etymology Dictionary suggest the name is a blend of the words gene and chromosome.
Genomics is an interdisciplinary field of molecular biology focusing on the structure, function, evolution, mapping, and editing of genomes.A genome is an organism's complete set of DNA, including all of its genes as well as its hierarchical, three-dimensional structural configuration.

Using these x-rays and information already known about the chemistry of DNA, James D. Watson and Francis Crick demonstrated the molecular structure of DNA in 1953. [25] [26] Together, these discoveries established the central dogma of molecular biology, which states that proteins are translated from RNA which is transcribed by
The OED suggests that its third definition originated as a back-formation from mitome, [7] Early attestations include biome (1916) [8] and genome (first coined as German Genom in 1920 [9]). [10] The association with chromosome in molecular biology is by false etymology.
Gene nomenclature was established by the HUGO Gene Nomenclature Committee (HGNC), a committee of the Human Genome Organisation, for each known human gene in the form of an approved gene name and symbol (short-form abbreviation), which can be accessed through a database maintained by HGNC. Symbols are chosen to be unique, and each gene has only ...
In a 1998 analysis of the E. coli genome, a large number of genes with unknown function were designated names beginning with the letter y, followed by sequentially generated letters without a mnemonic meaning (e.g., ydiO and ydbK). [9]
In molecular biology and genetics, DNA annotation or genome annotation is the process of describing the structure and function of the components of a genome, [2] by analyzing and interpreting them in order to extract their biological significance and understand the biological processes in which they participate.
