- Gene regulation is the process of controlling the expression of specific genes in cells1. Gene regulation involves a variety of mechanisms, such as regulatory sequences, regulatory genes, and gene regulatory networks1234. Gene regulation determines the production of gene products, such as proteins and RNA, which affect the function of the cell12. Gene regulation is an essential feature of all living organisms and viruses3.

Regulation of gene expression is an essential feature of all living organisms and viruses.en.wikipedia.org/wiki/Regulatory_sequenceA regulator gene, regulator, or regulatory gene is a gene involved in controlling the expression of one or more other genes. Regulatory sequences, which encode regulatory genes, are often at the five prime end (5') to the start site of transcription of the gene they regulate.en.wikipedia.org/wiki/Regulator_gene - People also ask
