Regulator in genetics
WebGene regulation and expression. The activity of a cell depends on its ability to use the information in the genes to make specific amounts of specific proteins at specific times and places. Developmental genetics examines how patterns of gene expression and regulation control the development of a multicellular organism from a single cell. WebGene regulation is the process of controlling which genes in a cell's DNA are expressed (used to make a functional product such as a protein). Different cells in a multicellular …

WebFeb 19, 2013 · The meaning of REGULATORY GENE is a gene that regulates the expression of one or more structural genes by controlling the production of a protein (such as a genetic repressor) which regulates their rate of transcription. A 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. In addition, these sequences can also be … See more Promoters reside at the beginning of the gene and serve as the site where the transcription machinery assembles and transcription of the gene begins.
