Regulation of gene expression, or gene regulation, includes a wide range of mechanisms that are used by cells to increase or decrease the production of specific gene products (protein or …A gene is expressed in a cell to perform one or many functions. It helps a cell respond to various internal and external changes. Genes control the synthesis of proteins and proteins control the structure, metabolic functions and development of an organism. The two steps involved in the synthesis of a protein are transcription and translation.Information from a gene is used to build a functional product in a process called gene expression. A gene that encodes a polypeptide is expressed in two steps. In this process, information flows from DNA. protein, a directional relationship known as the central dogma of …The regulation of gene expression in prokaryotic cells occurs at the transcriptional level. Simply stated, if a cell does not transcribe the DNA’s message into mRNA, translation (protein synthesis), does not occur. Bacterial genes are often organized into common pathways or processes called operons for more coordinated regulation of expression.
