PCAT Biological Processes – Meiosis and Mitosis
- Oct 24, 2017
- PCAT Question of the Day
Which of the following phases are common to cells undergoing meiosis and mitosis?
- G0 phase
- G2 phase
- S phase
- I only
- I and II only
- II and III only
- I, II, and III
This question asks the examinee to determine a phase within the cell life cycle that is common to both mitotic-dividing cells and meiotic-dividing cells. The cell cycle is composed of interphase and M phase. In mitotic-dividing cells, interphase includes G1 phase, S phase, G2 phase, and in highly specialized cells, such as neurons, a G0 phase. Similarly, meiotic-dividing cells include interphase and M phase, but germ cells do not exist in growth arrest phase (G0). Thus, II and III are correct making answer choice C the best answer.
