Question

Messenger RNA longevity is often related to the length of what feature of the molecules?

1) the 5' UTR
2) the promoter
3) the operator
4) the poly(A) tail
5) the first intron

Answer 1

The longevity of messenger RNA (mRNA) is often related to the length of the poly(A) tail feature of the molecule. Hence the correct answer is option 4

Step-by-step explanation:

The longevity of messenger RNA (mRNA) is often related to the length of the poly(A) tail feature of the molecule.

Many factors contribute to mRNA stability, and one of them is the length of the poly(A) tail. The longer the poly(A) tail, the more stable the mRNA, allowing it to exist in the cytoplasm longer and be translated into protein.

Hence the correct answer is option 4
