A biologist measured the amount of DNA in several single diploid cells taken from a culture. He knew that these cells could divide mitotically, but not meiotically. His data is shown below: Cell Number and DNA content in micrograms: Cell 1 (11.1 micrograms) Cell 2 (5.4 micrograms) Cell 3 (7.3 micrograms) Cell 4 ( 10.9 micrograms) Cell 5 (5.6 micrograms) Cell 6 (8.6 micrograms) Cell 7 (11.0 micrograms) Which of these cells have most likely just completed mitosis and cytokinesis?
