Gene Regulation

Abstract

Genes store life data and information in genetic language. In accordance with the Central Dogma, life data are located in DNA sequences in the format of genes and the information is transcribed into transient molecules of RNA and finally the coding RNAs are translated into proteins. But the role of RNAs is pivotal. In other words, gene regulation (including expression or suppression) is an amazing and vital process that is composed of two central networks; DNAs and RNAs. Today, the principal and fundamental role of RNA molecules is revealed and it is known that the regulation of genes is directly controlled by DNA and RNA molecules. The diversity of RNAs in different cells and in particular Eukaryotic cells explains the importance of RNAs in gene regulation.
