Gene regulation is a process in which a cell determines which genes it will express and when. Every cell in the human body contains a complete copy of that person's DNA, with tens of thousands of potentially viable genes. Genes cannot be expressed at once, so cells must decide which genes to turn on and which genes to turn off. For example, a skin cell turns on the genes that make it a skin cell, while a bone cell would leave these genes turned off. It is useful for gene regulation, a valuable for cell function. As a cell moves through its life, it has different needs and functions, which can be addressed with the use of this process to determine which genes are expressed and when. cells can adapt to environmental changes, such as an injury which requires repair by activating new genes. For the cell, gene regulation can be accomplished in a number of different ways, with one of the most common simply being regulation of the rate at which RNA transcription occurs. Genes can also be deactivated by changing the structure of the DNA in an individual cell to turn them off or on.
