In this article we will discuss about the function of regulator gene. The genetic basis for induction and repression was studied for several years by Jacob and Monod at the Pasteur Institute in Paris. They investigated regulation of the activities of genes which control fermentation of lactose through synthesis of the enzyme β-galactosidase in E. […]

Biology Notes on DNA Methylation | Genetics
Article Shared by
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 this article we will discuss about the details of structural genes. Structural Genes: They control amino acid sequence of a protein by producing mRNA. There are as many structural genes as there are proteins which are regulated. Either a single mRNA is transcribed from each structural gene or, all the structural genes of an […]
