Cells in the body function because of [[DNA]]. DNA sits within the [[Cell nucleus|nucleus of a cell]]. Here, parts of DNA are [[Transcription (biology)|copied]] and sent to the body of the cell via [[RNA]].{{sfn|Ganong's|2016|p=16}} The RNA is then used to [[translation (biology)|create]] [[protein]]s, which form the basis for cells, their activity, and their products. Proteins dictate cell function and gene expression, a cell is able to self-regulate by the amount of proteins produced.<ref>{{Cite web|title=Gene Expression {{!}} Learn Science at Scitable|url=http://www.nature.com/scitable/topicpage/gene-expression-14121669|website=www.nature.com|language=en|url-status=dead|archive-url=https://web.archive.org/web/20101031053632/http://www.nature.com/scitable/topicpage/gene-expression-14121669|archive-date=31 October 2010|access-date=29 July 2017}}</ref> However, not all cells have DNA; some cells such as mature [[Red blood cell|red blood cells]] lose their nucleus as they mature.
