13. The diagram below represents a cell found in some complex organisms. The enlarged section represents an organelle, labeled X, found in this cell. Part A: Identify organelle X. State the process that this organelle performs. (1 point)

Part B: Identify two materials that are needed for this process to occur, and then identify one molecule produced by this organelle and explain why it is important to the organism. (3 points)

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.
