Question

Why can’t eukaryotic transcription regulation by attenuation?

Short answer

Eukaryotic transcription cannot be regulated by attenuation because the transcription and translation occur in the different sites.

Step-by-step solution

Translation in eukaryotes

In eukaryotes, transcription occurs in the nucleus but translation occurs in the cytoplasm but prokaryotes both translation and transcription occurs in the cytoplasm so that the transcription can be regulated attenuated.

Site of translation

But in eukaryotes,the site of transcription and translation occurs in the different sites so that for translation the ribosome should be transferred into the cytoplasm for content with m RNA. Contents of m-RNA are a more essential step for attenuation.

Hence, the transcription in eukaryotes cannot be regulated by attenuation.
