Abstract:
The potential of cells to guide their genome and configure genes to express at a given time and in response to specific stimuli is pivotal to regulate cellular processes such as tissue differentiation, organogenesis, organismal development, homeostasis, and disease. In this review, we focus on the diverse mechanisms involved in DNA replication and its degradation, mRNA synthesis, and associated regulation such as RNA capping, splicing, tailing, and export. mRNA turnover including Decapping, deadenylation, RNA interference, and Nonsense mediated mRNA decay followed by protein translation, post-translational modification, and protein turnover. We highlight recent advances in understanding the complex series of molecular mechanisms responsible for the remarkable cellular regulatory mechanisms.

The Central Dogma
RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...

DNA and RNA
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria. In prokaryotes,...
