2. Gene Regulation

How is gene expression regulated?

There are various forms of gene regulation, that is, mechanisms for controlling which genes get expressed and at what levels. However, a lot of gene regulation occurs at the level of transcription.Bacteria have specific regulatory molecules that control whether a particular gene will be transcribed into mRNA.

Often, these molecules act by binding to DNA near the gene and helping or blocking the transcription enzyme, RNA polymerase. Let’s take a closer look at how genes are regulated in bacteria.
