Omics

Omics is a term used in modern genetics. It is used for terms which end in the suffix "-omics", such as genomics.
The suffix -ome is used for the objects of study, such as the genome, proteome or metabolome. The "-ome" refers to a "totality" of some sort. 
Functional genomics aims at identifying the functions of as many genes as possible of a given organism.
Many "omes" beyond the original "genome" have been adopted by research scientists. "Proteomics" has become well-established as a term for studying proteins at a large scale.
