One function of the poly-a tail on eukaryotic mrna sequences is to 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 have the same functions as eukaryotic poly-a tails, because this process is highly conserved throughout different species.
b. prokaryotic poly-a tails are composed of a different molecular structure compared with eukaryotic poly-a tails.
c. prokaryotic poly-a tails have other functions, because prokaryotes don't have nuclei.
d. prokaryotic poly-a tails aren't important, because prokaryotes don't have nuclei.
