Genomics and Proteomics

Proteomics and Genomics

Proteomics is a large study of proteome. A proteome is a set of proteins produced in an organism, system, or biological situation. For example, it can represent a proteome of a species (such as Homo sapiens) or an organ (such as the liver). Proteome is not constant. It varies from cell to cell and changes over time. To some degree, the proteome reflects the underlying transcriptome. However, protein activity (often measured by the kinetics of processes involving proteins) is regulated by many factors, in addition to the expression level of the relevant gene.

Genomics is a department of biotechnology concerned with applying the procedures of genetics and atomic science to the hereditary mapping and DNA sequencing of sets of qualities or the total genomes of selected living beings, with organizing the results in databases, and with applications of the information (as in pharmaceutical or science)
