The Cell Cycle Questions and Answers
Rated A+
Cell Cycle ✔✔An ordered sequence of events in the life of a cell
Mitosis ✔✔A process of nuclear division in eukaryotic cells conventionally divided into five stages: prophase, prometaphase, metaphase, anaphase, and telophase. Mitosis conserves chromosome number by allocating replicated chromosomes equally to each of the daughter nuclei.
Prophase
Metaphase
Anaphase
Telophase ✔✔What are the 4 stages of mitosis?
Prophase ✔✔The first stage of mitosis, chromosomes become visible when stained a viewed under a microscope; Miotic spindle begins to form
Metaphase ✔✔The 2nd stage of mitosis, in which the spindle is complete and the chromosomes, attached to microtubules at their kinetochores, are all aligned at the metaphase plate.
Anaphase ✔✔The 3rd stage of mitosis, in which the chromatids of each chromosome have separated and the daughter chromosomes are moving to the poles of the cell.
Telophase ✔✔The 4th and final stage of mitosis, in which daughter nuclei are forming and cytokinesis has typically begun.
Cytokinesis ✔✔The division of the cytoplasm to form two separate daughter cells immediately after mitosis, meiosis I, or meiosis II.
Cell Division ✔✔Process by which a cell divides into two new daughter cells
Chromosomes ✔✔A cellular structure carrying genetic material, found in the nucleus of eukaryotic cells. Each chromosome consists of one very long DNA molecule and associated proteins
Chromatin ✔✔DNA and protein that makes up chromosomes
G1 Phase ✔✔The first gap, or growth phase, of the cell cycle, consisting of the portion of interphase before DNA synthesis begins.
S Phase ✔✔The synthesis phase of the cell cycle; the portion of interphase during which DNA is replicated.
G2 Phase ✔✔The second gap, or growth phase, of the cell cycle, consisting of the portion of interphase after DNA synthesis occurs.
Centrosome ✔✔A structure present in the cytoplasm of animal cells that functions as a microtubule-organizing center and is important during cell division. A centrosome has two centrioles.
Cell Plate ✔✔In a plant cell, midline of dividing cells. Becomes the cell wall eventually.
G0 ✔✔A nondividing state occupied by cells that have left the cell cycle, sometimes reversibly.
Cyclin ✔✔A cellular protein that occurs in a cyclically fluctuating concentration and that plays an important role in regulating the cell cycle.
Cancer ✔✔A disease in which some body cells grow and divide uncontrollably, damaging the parts of the body around them.
Apoptosis ✔✔Programmed cell death
Spindle ✔✔Fanlike microtubule structure that helps separate the chromosomes during mitosis
Centrioles ✔✔Are located near the nucleus and help to organize cell division.
