How short must the poly(A)tail get to cause the mRNA to be degraded rapidly?
A)1 adenosine residue
B)about 10 adenosine residues
C)about 100 adenosine residues
D)about 30 adenosine residues
E)about 75 adenosine residues

Question

Quizplus · Accepted Answer

The poly(A) tail typically ranges from 150-250 adenosine residues in length. However, degradation can begin once the tail reaches about 30 adenosine residues. Therefore, choice D is the most accurate answer.
