The answer: different gene regulation! Gene regulation is how a cell controls which genes, out of the many genes in its genome, are “turned on” (expressed). Thanks to gene regulation, each cell type in your body has a different set of active genes – despite the fact that almost all the cells of your body contain the exact same DNA.

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 …Gene expression is the process by which the information in a gene is used to produce a functional product, such as a protein. In prokaryotes, the regulation of gene expression plays a crucial role in the adaptation of the organism to its environment and in the coordination of metabolic processes. Prokaryotes, such as bacteria, have a relatively ...Gene Regulation in Prokaryotes: In bacteria the expression of genes is controlled by extracellular signals often present in the medium in which bacteria are grown. These signals are carried to the genes by regulatory proteins. Regulatory proteins are of two types. They are positive regulators called activators and negative regulators called ...The expression of a gene is a highly regulated process. In multicellular organisms it allows for cellular differentiation, in single-celled organisms like prokaryotes, it primarily ensures that a cell’s resources are not wasted making proteins that the cell does not need at that time.Summarize the steps of transcription.
