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
Just as stated and also explained, the correct answer is a long chain of adenine nucleotides is added to the 3' end of mRNA during terminationof transcription. That is the only statement that is true about the polyadenylation mechanism. Hope this is helpful
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
