Exam Questions and Answers | A+ Score
Assured
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
Haploid Number of Chromosomes In Humans - 🧠 ANSWER ✔✔23
Control center of the cell; a part of the cell containing DNA and RNA and
responsible for growth and reproduction - 🧠 ANSWER ✔✔Nucleus
