WebDec 30, 2024 · As with almost every comparison with prokaryotic systems, regulation of eukaryotic transcription is much more complex than prokaryotic gene control, although still based on similar mechanisms of activators and repressors. There is no close eukaryotic equivalent to operons, though: eukaryotic genes are always transcribed one per mRNA. 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 ...

WebJun 9, 2024 · Like prokaryotic cells, eukaryotic cells also have mechanisms to prevent transcription. Transcriptional repressors can bind to promoter or enhancer regions and block transcription. Like the transcriptional activators, repressors respond to external stimuli to prevent the binding of activating transcription factors.
