BIOS-251: Exam 2 Review Q&A Solution A+ Cell division in which the nucleus divides into nuclei containing the same number of chromosomes - Correct Ans-Mitosis The resting phase of mitosis. Cell gr ... ows, performs its normal functions, and prepares for division; consists of G1, S, and G2 phases - Correct Ans-Interphase Cells that have left the cycle and cease dividing for a long time (or permanently) - Correct Ans-G Zero (G0) Phase The first gap, or growth phase, of the cell cycle, consisting of the portion of interphase before DNA synthesis begins. - Correct Ans-G1 Phase The synthesis phase of the cell cycle; the portion of interphase during which DNA is replicated. - Correct Ans-S Phase The second gap, or growth phase, of the cell cycle, consisting of the portion of interphase after DNA synthesis occurs.
