Many prokaryotic genes are organized in operons, linked genes transcribed into a single mRNA encoding two or more proteins. Operons usually encode proteins with related functions.Control of Gene Expression. By gene expression we mean the transcription of a gene into mRNA and its subsequent translation into protein. Gene expression is primarily controlled at the level of transcription, largely as a result of binding of proteins to specific sites on DNA. In 1965 Francois Jacob, Jacques Monod, and Andre Lwoff shared …
Compare prokaryotic and eukaryotic gene regulation. To understand how gene expression is regulated, we must first understand how a gene codes for a functional protein in a cell. The process occurs in both prokaryotic and eukaryotic cells, just in slightly different manners.
