Question
10. Which of the following best describes what occurs during mRNA processing?
Select one:
a. A poly-A tail is added to the 5’ end, a cap is added to the 3’ end, introns are removed and exons are spliced together
b. A cap is added to the 5’ end, a poly-A tail is added to the 3’ end, introns are removed and exons are spliced together
c. A poly-A tail is added to the 5’ end, a cap is added to the 3’ end, exons are removed and introns are spliced together
d. A cap is added to the 5’ end, a poly-A tail is added to the 3’ end, exons are removed and introns are spliced together
Explanation / Answer
10.Ans- b. A cap is added to the 5’ end, a poly-A tail is added to the 3’ end, introns are removed and exons are spliced together
During RNA processing, a cap is added to the 5' end of the RNA transcript and a poly-A tail is added to the 3' end. In splicing, introns are removed and the exons are spliced together.
