The process of gene expression is used by all known life - eukaryotes (including multicellular organisms), prokaryotes (bacteria and archaea) Regulation of gene expression: Regulation of gene expression includes a wide range of mechanisms that are used by cells to increase or decrease the production of specific gene products (protein or RNA). Replication level– Any error in copying the DNA may result in an altered expression. Regulation of Gene Expression in Prokaryotes - PowerPoint PPT Presentation. 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 RNA).Sophisticated programs of gene expression are widely observed in biology, for example to trigger developmental pathways, respond to environmental stimuli, or adapt to new food sources. 03/26/14 29Biochemistry For Medics 30.
