【相关描述】Bioinformatists and molecular biologists are thought to be among the first scientists to start to apply the -ome suffix in several scientific areas.
Bioinformatics is an information science that analyzes life processes using computational tools for solving biological problems and to give direction or an overview in biology.
Ome and omics are convenient ways to describe a holistic way of looking at complex systems. In the mid 1990's bioinformatists started realizing the convenience of -omics and used terms for many fields; such as, metabolome, textome, interactome, bacteriome, eukaryome, functome, patentome, neurome and so on.
Omics was coined by scientists to present the realization of the importance of information processing in biology that was proposed by many biologists and as such, it was made possible by the development of personal computers and personal computer operating systems; such as, Windows, Linux, and Apple.
