- Define repressors?arrow_forwardWhich statement describes a difference between transcription in eukaryotic and prokaryotic cells? In eukaryotes, transcription occurs simultaneously with translation, while transcription in prokaryotes must complete before translation can begin. In eukaryotes, transcription is completed by an RNA polymerase, while transcription in prokaryotes is completed with a DNA polymerase. In eukaryotes, transcription produces an RNA molecule, while transcription in prokaryotes produces a DNA molecule. In eukaryotes, transcription produces a monocistronic RNA, while transcription in prokaryotes produces a polycistronic RNA. In eukaryotes, transcription produces an DNA molecule, while transcription in prokaryotes produces a RNA molecule.arrow_forwardDefine transcription unit.arrow_forward
