A molecular biologist is working with an unknown enzyme. In order to test the living conditions of this enzyme, the biologist places the unknown enzyme in two separate vials. In the first vial, the pH is set at 2.0 while the temperature is at 36° C. In the second vial, the pH is set at 11.5 and the temperature is set at 26° C. What should happen in this experiment? *

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 are composed of a different molecular structure compared with eukaryotic poly-a tails. 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 aren't important, because prokaryotes don't have nuclei. d. prokaryotic poly-a tails have other functions, because prokaryotes don't have nuclei.
