BIOS 251 Exam 2 Test Bank | UPDATED ACTUAL Exam Questions
and CORRECT Answers Graded A+ 100% Verified
Question 1.
The resting phase of mitosis. Cell grows, performs its normal functions, and prepares for
division; consists of G1, S, and G2 phases .
Answer: Interphase
Question 2.
Cells that have left the cycle and cease dividing for a long time (or permanently) .
Answer: G Zero (G0) Phase
Question 3.
The first gap, or growth phase, of the cell cycle, consisting of the portion of interphase
before DNA synthesis begins. .
Answer: G1 Phase
Question 4.
The synthesis phase of the cell cycle; the portion of interphase during which DNA is
replicated. .
Answer: S Phase
Question 5.
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 .
Answer: 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 . Answer: Prophase
Question 6.
Second phase of mitosis, during which the chromosomes line up across the center of the
cell .
Answer: Metaphase
Question 7.
The third phase of mitosis, during which the chromosome pairs separate and move
toward opposite poles .
, Answer: Anaphase
Question 8.
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. .
Answer: Telophase
Question 9.
Division of the cytoplasm during cell division .
Answer: Cytokinesis
Question 10.
Cell division that produces reproductive cells (gametes) in sexually reproducing
organisms .
Answer: Meiosis
Question 11.
Compare and Contrast Mitosis and Meiosis .
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.

growth and reproduction .
Answer: Nucleus
Question 14.
Processes and transports proteins made at attached ribosomes; synthesizes
phospholipids .
Answer: Rough Endoplasmic Reticulum (RER)
