Let us make an in-depth study of the regulation of gene expression in prokaryotes. All the activities of an organism are controlled by genes. Most of the genes of an organism express themselves by producing proteins. The genes which produce proteins are called structural genes or cistrons. Every cell of an organism posses all the genes. But all of them [...]
Let us discuss about the two types of gene expression regulation. The two types of gene expression regulation are: (1) Negative Regulation and (2) Positive Regulation. And also discuss about some important terms used in connection with the regulation of gene expression. Most of the genes of an organism produce specific proteins (enzymes), which, in turn produce specific phenotypes. The [...]
In this article, we propose to discuss the regulation of gene expression in eukaryotes with diagram. Operons are also functional in eukaryotes. Likewise, they are of two types, inducible and repressible. Gene regulation of eukaryotes is slightly complex as compared to that of prokaryotes. 1. Different structural genes connected to a metabolic pathway do not often lie adjacent to one [...]
