How is gene expression a regulated process
Web14 apr. 2024 · Regulation of microbial production of secondary BAs is not well understood, particularly the production of 7-dehydroxylated BAs, which are the most potent agonists for host BA receptors. The 7-dehydroxylation of cholic acid (CA) is well established and is linked to the expression of a bile acid-inducible (bai) operon responsible for this process. WebRegulation of Gene Expression Gene expression is the process by which the instructions present in our DNA are converted into a functional product, such as a protein. This …
