QUESTIONS AND VERIFIED ANSWERS
Cell division in which the nucleus divides into nuclei containing the same number
of chromosomes - ANSWER- Mitosis
The resting phase of mitosis. Cell grows, performs its normal functions, and
prepares for division; consists of G1, S, and G2 phases - ANSWER- Interphase
Cells that have left the cycle and cease dividing for a long time (or permanently) -
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. - ANSWER- G1 Phase
The synthesis phase of the cell cycle; the portion of interphase during which DNA
is replicated. - ANSWER- 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 - 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
Second phase of mitosis, during which the chromosomes line up across the center
of the cell - ANSWER- Metaphase
The third phase of mitosis, during which the chromosome pairs separate and move
toward opposite poles - 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. - ANSWER- Telophase
Division of the cytoplasm during cell division - ANSWER- Cytokinesis
Cell division that produces reproductive cells (gametes) in sexually reproducing
organisms - ANSWER- Meiosis
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.
Number of Chromosomes in Humans... - ANSWER- 46
