1. 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?
a. 1, 4, and 7
b. 3 and 6
c. 2, 3, 5, and 6
d. 2 and 5
e. No conclusion can be drawn from the data provided.
