Question

One function of the poly-A tail on eukaryotic mRNA sequences is to help the mRNA

be transported from the nucleus to the cytoplasm. Prokaryotic mRNA also has a
poly-A tail. Choose the best explanation of the prokaryotic poly-A tail.

A. Prokaryotic poly- A tails aren’t important, because prokaryotes don’t have nuclei
B. Prokaryotic poly A tails have the same functions as eukaryotic poly-A tails, because this process is highly conserved throughout different species.
C. Prokaryotic poly A tails are composed of a different molecular structure compared with eukaryotic poly- A tails
D. Prokaryotic poly- A tails have other functions, because prokaryotes don’t have nuclei

Answer 1

Answer: D

Prokaryotic poly-A tails have other functions, because prokaryotes don't have nuclei.

Explanation: It's an extension of the prokaryotic cell, because of its lack of a nucleus.
