Cell Cycle

by Max DeJesus

Step 1: Interphase

What Happens:


  • Cell is not dividing
  • DNA copied
  • Organelles copied
  • Cell increase in size
  • Cell does normal activities
  • Longest part of cell cycle (80-85% of time)
  • DNA is in strands


Organelles:


  • nucleus
  • nuclear membrane
  • DNA
  • centrioles
  • spiundle fibers

Step 2: Prophase

What Happens:


  • DNA is packaged into chromosomes
  • By the end of this stage, nuclear membrane and nucleus are gone


Organelles:

  • DNA (in chromosomes)
  • centrioles
  • spindle fibers

Step 3: Metaphase

What Happens:

  • Chromosomes line up at center of cell
  • Spindle fibers from centriole attach to chromosomes


Organelles:

  • DNA (in chromosomes)
  • centrioles
  • spindle fibers

Step 4: Anaphase

What Happens:

  • Chromosomes separate
  • Spindle fibers pull halved chromosomes to one side of cell


Organelles:

  • DNA (in chromosomes)
  • centrioles
  • spindle fibers

Step 5: Telophase

What Happens:

  • Nuclear membrane forms around new groups of chromosomes
  • Cell wall pinches in to form two new daughter cells


Organelles:

  • DNA (in chromosomes)
  • nuclear membrane
  • centrioles
  • spindle fiber

Step 6: Cytokinesis

What Happens:

  • Cells divide into two'


Organelles:

  • nucleus
  • nuclear membrane
  • centrioles
  • spindle fibers
  • DNA (in chromosomes)
