Cell cycle mitosis

Cell Cycle & Mitosis


Cell cycle

Cell Cycle

  • Cell Cycle = IMPAT

  • I = Interphase

  • MPAT= Stages of Mitosis


Cell cycle1

Cell Cycle


Mitosis

Mitosis

  • Interphase (stage before mitosis!)

    • G1 + S + G2 = Interphase

    • Cell grows, makes more cytoplasm and organelles duplicate, copies DNA, and gets ready to divide


Prophase

Prophase

  • Chromosomes shorten & thicken

  • Centrioles move to opposite poles of the cell

  • Spindle fibers extend from the centrioles toward each chromosome

  • Nuclear membrane dissolves


Metaphase

Metaphase

  • During late prophase chromatids begin to move toward the cell equator (metaphase plate)

  • At metaphase the chromatids are aligned at the equator


Anaphase

Anaphase

  • Chromatids begin to move apart, toward opposite poles


Telophase

Telophase

  • Chromosomes reach opposite poles of the cell

  • Spindle fibers dissolve

  • Nuclear membrane reforms at each end of the cell


Cytokinesis

Cytokinesis

  • Cytokinesis = splitting of the cytoplasm

  • Not an actual “phase of mitosis”.

  • The division of cytoplasm after separation of the chromosomes

  • In plant cells, a new cell wall forms to divide the two daughter cells (CELLPLATE)

  • In animal cells, the cleavage furrow forms
