Question 1 of 9
Question
Many prokaryotic RNA molecules do not undergo posttranscriptional processing. What is the purpose of RNA processing in eukaryotic cells?
Correct.
Incorrect.
Question
What would happen to an mRNA that doesn’t have a 5’ cap?
Correct.
Incorrect.
Question
Which splicing reactions happen first in the removal of introns from mRNA?
Correct.
Incorrect.
Question
Below are some events that occur during RNA processing. Select the answer that best represents the order in which they occur.
1. Cap-binding protein binds to 5’ cap 2. Polyadenylate polymerase binds and adds poly(A) tail 3. Splicing 4. mRNA transcription continues 5. Poly(A) binding protein binds to poly(A) tail 6. Exonuclease cuts at GU-rich section 7. Polyadenylation factor binds to mRNA 8. Guanylyltransferase binds to 5’ end of mRNA
Correct.
Incorrect.
Question
What do most of the reactions that drive RNA processing have in common?

Question
Does the polyadenylate polymerase require an RNA template?
Correct.
Incorrect.
Question
RNA processing occurs simultaneously with transcription.
Correct.
Incorrect.
Question
What is the importance of the branch point in introns?
