Question

In polyadenylation, the enzyme polyA polymerase adds a chain of 100 to 250 adenine nucleotides to the mRNA molecule. The functions of polyadenylation include:

(i) Polyadenylation provides stability and prevents degradation.
(ii) It exports the mature mRNA from the nucleus to be translated to protein.

Accepted Answer

Both (i) and (ii) are correct

Answer

(i) is correct and (ii) is incorrect

Answer

(ii) is correct and (i) is incorrect
