WebBacteria 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. headstone textureWebIn this article we will discuss about the regulation of levels of transcription by DNA methylation. In most higher plants and animals, the DNA is often modified after synthesis by the enzymatic conversion of many cytosine bases to 5-methylcytosine bases (Fig. 5.8).
