Inspired by the terms genome and genomics, other words to describe complete biological datasets, mostly sets of biomolecules originating from one organism, have been coined with the suffix -ome and -omics.
For example, the genome contains the ORFeome, which gives rise to the transcriptome, which is translated to the proteome.
Other terms are overlapping and refer to the structure and/or function of a subset of proteins (e.g. glycome, kinome).
An omicist is a scientist who studies omeomics, cataloging all the “omics” subfields.
[1] Omics.org is a Wiki that collects and alphabetically lists all the known "omes" and "omics.
