     Cell Biology (Mitosis)
1. All living organisms are composed of
    cells.
e. cells divide to increase their numbers
    through a process of mitosis, which
    results in two daughter cells with
    identical sets of chromosomes.
       Cell Cycle 6 phases
Interphase
Prophase
Metaphase
                  Phases of
Anaphase          Mitosis
Telophase
Cytokinesis
The Complete
 Cell Cycle
Chromosome Structure



         Centromere
        Chromosome Structure
So 1 chromatid
+ 1 chromatid =
1 Chromosome



  1 chromatid
                         1 chromatid
                Interphase
THE CELL:
grows  to it’s mature size
makes a _____ of its
           Copy
 DNA
               Divide
prepares to _______ into
 two cells
The DNA
condenses
                   Prophase
the __________ condenses
      Chromatin
 (gets thicker) to form
 chromosomes, which are
 two chromatids attached by
 a ____________.
    Centromere
_______ fibers stretch out to
  Spindle
 opposite ends of the cell
the   nucleus breaks down
               Metaphase
     __________
the Chromosomes    line
 up in the middle of the
 cell
spindle fibers attach to
 the __________ of the
      Centromere
 chromosomes
                  Anaphase
____________
  Centromeres       split and the
 chromatids separate
chromatid to opposite ends
 of the cell being pulled by
       Spindle Fibers
 the ___________
the cell begins to become
 stretched out
               Telophase
the  __________
       Nucleus
 reappears – two nuclei
 but one cell
chromosomes begins
 to loosen up (start to
 become string again)
              Cytokinesis
the  cell divides and two
          Daughter
 new ___________ cells
 are formed
chromosomes loosen up
 and become chromatin
 again
