Does the polyadenylate polymerase require an RNA template Ye

Does the polyadenylate polymerase require an RNA template?

Yes, the template for polyadenylation is UUU … U.

Yes, the template for polyadenylation is found in the template DNA strand.

No, a template is not needed for the addition of the poly(A) tail.

No, the polyadenylate polymerase never binds to the mRNA. Yes, the template for polyadenylation is TTT … T.

Solution

Answer C: No, a template is not needed for the addition of the poly(A) tail.

The addition of poly A tails to mRNA is called Polyadenylation. This is done by polyadenylate polymerase. It helps in transcription termination and nulear transport of mRNA. It has also a role in and translation. It also protects mRNA from degradation.
