WebDec 10, 2024 · How are genes turned on and off in cells? Each cell expresses, or turns on, only a fraction of its genes. The rest of the genes are repressed, or turned off. The process of turning genes on and off is known as gene regulation. Gene regulation is an important part of normal development. How does a cell regulate the production of proteins? WebThe set of genes expressed in a cell determines the set of proteins and functional RNAs it contains, giving it its unique properties. In eukaryotes like humans, gene expression involves many steps, and gene regulation can occur at any of these steps. However, many genes are regulated primarily at the level of transcription.

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. canal history of manchester
