What is the best explanation for how chemical energy is transferred within cells A. The chemical reaction that removes the bond that joins the adenine molecule and a phosphate group absorbs energy when broken.

B. The chemical reaction that removes the bond that joins the adenine molecule and a ribose sugar absorbs energy when broken.

C. The chemical reaction that removes the bond that joins the second phosphate and third phosphate group releases energy when broken.

D. The chemical reaction that removes the bond which joins the phosphate groups to the ribose sugar releases energy when broken.

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.
