Answer Happy

Recall the experiment performed by Yoshio Masui, in which a small amount of cytoplasm removed from a cell in mitosis was injected into another cell that is in interphase. The result of this manipulation is that the recipient cell rapidly enters mitosis. Predict the outcome of the experiment if it was performed in reverse: what would happen to the recipient cell if cytoplasm from a S-or G2-phase cell were transferred into a mitotic cell recipient? Select one: a. The recipient cell would return to S-or G2-phase, potentially leading to the re-replication of the DNA. O b. A cell cycle checkpoint would be activated, leading to a block of cell cycle progression. O c. No change would occur and the recipient cell would remain in mitosis. O d. None of the other answer choices are correct. O e. More than one of the other answer choices are correct.
