How many copies of each different DNA molecule will be found in a cell at the beginning of each of these stages of the mitotic cell cycle? G 2 of Interphase Prophase Cytokinesis A 1 1 2 B 1 2 1 C 2 1 2 D 2 2 2

Step-by-step solution

All the three stages mentioned occur after S-phase; thus, DNA is duplicated (DNA is twice in amount). Even though two nuclei have formed in the dividing cell, until the cytoplasm is completely divided, the single mother cell will have 2 copies of DNA. Once the cytokinesis has completed, each daughter cell will have a single copy of DNA. Hence, the answer is D.
