How do you know if a gene is turned on
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.
