WebRegulation at translational level occurs in different ways: (i) Activation and repression of translation: In eukaryotes the activator protein binds to mRNA and leads to the formation of hairpin structure which helps in ribosome binding with mRNA by the exposure of 5′ end. WebJul 30, 2024 · The regulatory region includes the promoter and the region surrounding the promoter, to which transcription factors, proteins encoded by regulatory genes, can bind. Transcription factors influence the binding of RNA polymerase to the promoter and allow its progression to transcribe structural genes.

WebFigure 1: Eukaryotic gene expression is regulated during transcription and RNA processing, which takes place in the nucleus, as well as during protein translation, which takes place … WebEukaryotic genes are not organized into operons, so each gene must be regulated independently. In addition, eukaryotic cells have many more genes than prokaryotic cells. Regulation of gene expression can happen at any of the stages as DNA is transcribed into mRNA and mRNA is translated into protein.

WebIn eukaryotic cells like photoreceptors, gene expression is often controlled primarily at the level of transcription. However, that doesn't mean transcription is the last chance for … WebBoth prokaryotic and eukaryotic cells have ways of co-regulating genes, but they use very different mechanisms to accomplish this goal. In prokaryotes, co-regulated genes are typically organized into an operon, where two or more functionally related genes are transcribed together from a single promoter into one long mRNA.
