Question

Which explains a difference between prokaryotic and eukaryotic gene reguation? A. Eukaryotes utilize operons, so they do not need to produce sections of mRNA. B. Prokaryotes process DNA in the nucleus, so genes do not need to be activated. C. Eukaryotes express all genes, so gene expression does not need to be regulated. D. Prokaryotes do not have mRNA, so they do not have processes to degrade mRNA.

Answer 1

Different between Prokaryotic and Eukaryotic Gene Regluation

Prokaryotes do not have DNA so they do not have mRNA. Therefore, they do not have processes to degrade mRNA explains a difference between prokaryotic and eukaryotic gene regulation.

• Eukaryotic cells have DNA which transcribed to RNA to form proteins.
• In prokaryotic cells, the control of gene expression is at the transcriptional level.

Answer 2

None of these statements is correct.

A. Eukaryotes utilize operons, so they do not need to produce sections of mRNA. This is not true, because prokaryotes utilize operons.

B. Prokaryotes process DNA in the nucleus, so genes do not need to be activated. This is not true because prokaryotes don’t have nucleus.

C. Eukaryotes express all genes, so gene expression does not need to be regulated. This is not true because eukaryotes express only certain genes, so, the regulation is high.

D. Prokaryotes do not have mRNA, so they do not have processes to degrade mRNA. This is not true because prokaryotes have mRNA.
