Differences in translation between prokaryotes and eukaryotes

Bacterial transcription is the process in which a segment of bacterial DNA is copied into a newly synthesized strand of messenger RNA (mRNA) with use of the enzyme RNA polymerase. The process occurs in three main steps: initiation, elongation, and termination; and the end result is a strand of mRNA that is complementary to a single stran… WebThe lac repressor acts as a lactose sensor. It normally blocks transcription of the operon, but stops acting as a repressor when lactose is present. The lac repressor senses lactose indirectly, through its isomer allolactose. Catabolite activator protein ( CAP) acts as a glucose sensor. WebYes, translation can occur anywhere ribosomes are located. There are free ribosomes that are present in the cytoplasm and ribosomes that are in the rough endoplasmic reticulum.

"WebThe maltose operon is an example of a positive control of transcription. When maltose is not present in E. coli, no transcription of the maltose genes will occur, and there is no maltose to bind to the maltose activator protein. This prevents the activator protein from binding to the activator binding site on the gene, which in turn prevents RNA polymerase … " - In bacteria transcription occurs in
