Gwhat are the differences between prokaryotic and eukaryotic gene expression? regulation of transcription is identical in both. prokaryotes do not use promoter sequences.5’ capping and 3' polyadenylation of mrna occurs only in eukaryotes. eukaryotes utilize multiple kinds of rna polymerase. prokaryotic mrna must move from the nucleus to the cytosol before translation. prokaryotic mrna is not spliced.

Prokaryotic gene expression:

The transcription of prokaryotes is different from the ekaryotes. Prokaryotes use the promoter sequence located at -10 and -35 position upstream of the DNA. The transcription is coupled with translation in prokaryotes in the cytoplasm. The spilicing of mRNA do not occur in eukaryotes.

Eukaryotic gene expression:

The regulation of transcription in eukaryotes is different from prokaryotes. The eukaryotic mRNA undergoes splicing and 3' polyadenylation and 5' capping occur in prokaryotes. Different kinds of RNA polymerase is required for the transcription of different RNA molecule. The transcription occurs in the nucleus.

it's a.true. i'm kind of smart.
