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.
