Transcription by DNA Methylation | Genetics

In 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). The extent of methylation varies from species to species; in mammals, from 2 to 7 percent of the [...]

Biology Notes on DNA Methylation | Genetics

The below mentioned article provides notes on DNA methylation. The DNA of many higher eukaryotes is modified after replication by methylation of cytosine bases at the 5-carbon position. The cytosines are incorporated in their normal unmodified form in the course of DNA replication; the methyl group (CH3) is then added by an enzyme DNA methylase. In mammals DNA is methylated [...]
