WebThere's one more difference I want to talk about in how translation happens in prokaryotes and eukaryotes and that is what the first amino acid in the polypeptide chain will be. So in … Webedit. In molecular biology and genetics, transcriptional regulation is the means by which a cell regulates the conversion of DNA to RNA ( transcription ), thereby orchestrating gene activity. A single gene can be regulated in a range of ways, from altering the number of copies of RNA that are transcribed, to the temporal control of when the ...
