Cell division in which the nucleus divides into nuclei containing the same
number of chromosomes - correct answer - Mitosis
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
Cells that have left the cycle and cease dividing for a long time (or
permanently) - correct answer - 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 answer - G1 Phase
The synthesis phase of the cell cycle; the portion of interphase during
which DNA is replicated. - correct answer - S Phase
, Page |2
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
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
Second phase of mitosis, during which the chromosomes line up across the
center of the cell - correct answer - Metaphase
The third phase of mitosis, during which the chromosome pairs separate
and move toward opposite poles - correct answer - 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 answer - Telophase
Division of the cytoplasm during cell division - correct answer - Cytokinesis
, Page |3
Cell division that produces reproductive cells (gametes) in sexually
reproducing organisms - correct answer - Meiosis
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.
Number of Chromosomes in Humans... - correct answer - 46
Haploid Number of Chromosomes In Humans - correct answer - 23
Control center of the cell; a part of the cell containing DNA and RNA and
responsible for growth and reproduction - correct answer - Nucleus
Processes and transports proteins made at attached ribosomes;
synthesizes phospholipids - correct answer - Rough Endoplasmic
Reticulum (RER)
Fatty acid and steroid synthesis; detoxifies toxic substances - correct
answer - Smooth Endoplasmic Reticulum (SER)
