Cell Cycle Assinment

By: Aubrey McDonald

Step #1: Interphase


  • The part of the cell cycle during which as cell is not dividing.

  • Cell grows to 2x its normal size.

  • Cell carries out normal activities.

  • DNA is copied. (organelles are also copied)

  • This is the longest part of the cell cycle. (80-85% of time cell is in this step.)

  • DNA is in strands.

DNA or Chromosomes, Nuclear membrane, Centrioles, and Spindle Fibers are present here.

Step #2: Prophase

  • In the nucleus of the cell, DNA forms chromosomes

  • Nuclear membrane disappears

DNA or Chromosomes, Nuclear membrane, Centrioles, and Spindle Fibers are present here.

Step #3: Metaphase

  • Chromosomes line up in the middle of the cell

  • Spindle Fibers from centrioles attach to chromosomes

DNA or Chromosomes, Centrioles, and Spindle Fibers are present here.

Step #4: Anaphase

  • Chromosomes separate

  • Each half is pulled to the opposite end of the cell

DNA or Chromosomes, Centrioles, and Spindle Fibers are present here.

Step #5: Telophase

  • A new nuclear membrane forms around each group of chromosomes (at either end of the cell).

DNA or Chromosomes, Centrioles, Nucleus, and Spindle Fibers are present here.

Step #6: Cytokinesis

  • The parent cell’s cytoplasm is divided between the two daughter cells.

  • The cell is pinched into two.


  • Cytokinesis = divides the cytoplasm

DNA or Chromosomes, Centrioles, Nucleus, and Spindle Fibers are present here.
