Question
2) Gene expression can be altered at the level of post-transcriptional processing more easily in eukaryotes than in prokaryotes because _____.
a.eukaryotic mRNAs get 5’ caps and 3’ tails
b.prokaryotes use ribosomes of different structure and size
c.prokaryotic transcripts are translated almost as soon as they emerge from the transcription bubble, while eukaryotic transcripts are kept in the nucleus before being exported to the cytoplasm for translation
d.prokaryotic genes are expressed mostly as mRNA, which is more stable as compared to tRNAs and rRNAs that are more common in eukaryotes
Explanation / Answer
c. prokaryotic transcripts are translated almost as soon as they emerge from the transcription bubble, while eukaryotic transcripts are kept in the nucleus before being exported to the cytoplasm for translation
