Determines if a gene is turned on or off

WebFor instance, there might be a controlling element that tells a gene to only turn on the liver and to stay off in all other cells. When the transcription factors bind the controlling element, they can help “turn on” the gene, which means transcribing the DNA sequence into RNA, which then can be turned into a protein. WebThis process does not alter the underlying genetic code. Instead it controls which genes are turned on or off in individual cells which determines the specific structure and function of the cell. Epigenetic modifications also help explain differences found between identical twins that share the same genetic code.
