Question

You are studying an mRNA whose polyA tail is rapidly shortened by a 3' to 5' exonuclease after exposure to something in the air. This means the polyA tail is shortened from its long form length of 200 nucleotides to only 10 nucleotides

A. What effect do you think the shortening of the polyA tail will have on the expression of the gene being effected

B. Describe two mechanisms by which the shortened polyA tail could have the effect you described above

Answer 1

Felt great to answer. Good luck!
