BIOS 251 Exam 2 Questions and Answers |Latest – Chamberlain
Question 1: Cell division in which the nucleus divides into
nuclei containing the same number of chromosomes
CORRECT ANSWER : Mitosis
Question 2: The resting phase of mitosis. Cell grows, performs
its normal functions, and prepares for division; consists of G1, S, and G2 phases
CORRECT ANSWER : Interphase
Question 3: Cells that have left the cycle and cease dividing for
a long time (or permanently)
CORRECT ANSWER : G Zero (G0) Phase
Question 4: The first gap, or growth phase, of the cell cycle,
consisting of the portion of interphase before DNA synthesis begins.

CORRECT ANSWER : G1 Phase
Question 5: The synthesis phase of the cell cycle; the portion of
interphase during which DNA is replicated.
CORRECT ANSWER : S Phase
Question 6: 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 ANSWER : G2 Phase
Question 7: 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 ANSWER : Prophase

Question 8: Second phase of mitosis, during which the
chromosomes line up across the center of the cell
CORRECT ANSWER: Metaphase
Question 9: The third phase of mitosis, during which the
chromosome pairs separate and move toward opposite poles
CORRECT ANSWER : Anaphase
Question 10: 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 ANSWER : Telophase
Question 11: Division of the cytoplasm during cell division
CORRECT ANSWER : Cytokinesis

Question 12: Cell division that produces reproductive cells
(gametes) in sexually reproducing organisms
CORRECT ANSWER : Meiosis
Question 13: Compare and Contrast Mitosis and Meiosis
CORRECT ANSWER : 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.
