Gene Regulation

 Gene regulation is how a cell controls which genes, out of the various genes in its genome, are "turned on" (expressed). due to gene regulation, each cell type in your body contains a different set of active genes – despite the very fact that just about all the cells of your body contain the precise same DNA. These different patterns of organic phenomenon cause your various cell types to possess different sets of proteins, making each cell type uniquely specialized to try and do its job.   For example, one amongst the roles of the liver is to get rid of toxic substances like alcohol from the bloodstream. To do this, liver cells express genes encoding subunits (pieces) of an enzyme called alcohol dehydrogenase. This enzyme breaks alcohol down into a non-toxic molecule. The neurons in a very person's brain don’t remove toxins from the body, so that they keep these genes unexpressed, or “turned off.” Similarly, the cells of the liver don’t send signals using neurotransmitters, in order that they keep neurotransmitter genes turned off. Gene regulation is that the process of controlling which genes in an exceedingly cell's DNA are expressed (used to create a functional product like a protein).
