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 grows, 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.
Growth and preparation for mitosis - Correct Ans-G2 Phase
First and longest phase of mitosis, during which the chromosomes become visible and the centrioles
separate and take up positions on the opposite sides of the nucleus - Correct Ans-Prophase
Second phase of mitosis, during which the chromosomes line up across the center of the cell - Correct
Ans-Metaphase
The third phase of mitosis, during which the chromosome pairs separate and move toward opposite
poles - Correct Ans-Anaphase
The final phase of cell division, between anaphase and interphase, in which the chromatids or
chromosomes move to opposite ends of the cell and two nuclei are formed. - Correct Ans-Telophase
Division of the cytoplasm during cell division - Correct Ans-Cytokinesis
Cell division that produces reproductive cells (gametes) in sexually reproducing organisms - Correct AnsMeiosis
Compare and Contrast Mitosis and Meiosis - Correct Ans-Mitosis produces two diploid (2n) somatic cells
that are genetically identical to each other and the original parent cell, whereas meiosis produces four
haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
