Which of the following is correct about the polyadenylation mechanism?
a: a long chain of adenine nucleotides is added to the 3' end of mrna during terminationof transcription
b: a long chain of uracil nucleotides is added to the 3' end of mrna during terminationof translation
c: a long chain of guanine nucleotides is added to the 3' end of mrna during termination of translation

The correct answer is A

Explanation:

Hello! Let's solve this!

Polyadenylation is the addition of many adenine bases bound to a messenger RNA molecule. This process occurs in the mRNA (messenger RNA), at the end of the transcription to then help the translation.

The correct answer is A: a long chain of adenine nucleotides is added to the 3 'end of mRNA during terminationof transcription

a and c are the answeres
