Eukaryotic gene regulation examples
Web15) The trp operon in E. coli is regulated in such a manner as to allow expression of the genes only when cellular levels of tryptophan are low. When tryptophan levels are adequate, the secondary structure of the mRNA halts translation. This form of regulation is known as A) attenuation. B) transcriptional regulation. WebFour types of enzymes are involved in gene regulation of prokaryotes. These are beta-galactosidase, galactosidase permease, transacetylase and RNA polymerase. The beta …
