The Cell Cycle

Cells grow, prepares for division, divides,

and begin cycle again.


IPMAT

Stages of the cell cycle

  • Interphase

  • Prophase

  • Metaphase

  • Anaphase

  • Telophase


Interphase

  • Most of the cell’s life time.

  • Chromosomes replicate.

  • Chromosomes are not visible under microscope.


Prophase

  • 1st stage of mitosis.

  • Chromosomes become visible through a microscope.

  • Nuclear envelope breaks down.

  • Chromosomes attach to spindle fibers.


Metaphase

  • Chromosomes line up in center of cell.

  • Chromosomes connected to spindle fiber at its centromere.


Anaphase

  • Sister chromatids separate and are pulled to opposite sides of the cell.


Telophase

  • New nuclear envelopes are formed around each set of chromosomes.


Cytokinesis

  • Cytoplasm pinches off to form two new cells, each with its own nucleus.
