Question
The DNA content of individual cells and the number of cells in each phase of a "cell cycle" can be determined using flow cytometry. Which of the following combinations of "phase of a cell cycle and its corresponding DNA content" can be considered normal?
(i) Diploid cells found in the G0 or G1 phase.
(ii) Cells with twice the normal DNA content in the early M phase.
(iii) Cells with intermediate amounts of DNA in the S phase.
(iv) Cells with twice the normal DNA content in the G2 phase.

Solution
The correct option is B (i), (ii), (iii) and (iv)
D. (i), (ii), (iii) and (iv)Solution : The diploid cells found in the G0 and G1 phase before starting the G2 or M phase but before anaphase. Cells with twice the normal DNA is in G2 or M phase that is mitosis phase. The S phase is characterized by intermediate DNA when the DNA starts replicating itself, till the entire replication process is complete.So the correct answer is " (i), (ii), (iii) and (iv)".
