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.
Keywords: Cellular regulation; Protein turnover; Replication; Transcription; Translation; mRNA turnover.
