MITOSIS the cell cycle

INTERPHASE (ANIMAL CELL)

• Animal cell interphase. The DNA has been
  replicated. Also, notice the increased cell size
  as the cytoplasm has been enlarged.

3
PROPHASE

• Animal cell in prophase. Notice that the DNA has
  been condensed into chromosomes.

4
METAPHASE

• Animal cell metaphase. Notice the chromosomes are
  lined up along the equator of the cell. Two poles
  representing each daughter cell are also formed
  by the spindle fibers.

5
ANAPHASE

• Animal cell anaphase. Notice the spindle fibers
  begin to pull the two sets of chromosome toward
  the opposite poles.

6
TELOPHASE

• Animal cell telophase. Notice the two poles begin
  to condense to form two nuclei. The cells begin
  to build the cell membrane in between.

INTERPHASE

• Interphase
• G1 cell grows and develops, chromosomes are
  uncoiled and invisible
• S chromosomes replicate and divide
• G2 chromosomes shorten and coil

9
PROPHASE

• Prophase
• chromosome condensation
• nuclear membrane disintegrates.
• The duplicated chromosome subunits (each one
  called chromotid) join together at the
  centromeres.
• At late prophase, the microtubular spindle begin
  to radiate from the centromeres.

10
METAPHASE

• Metaphase
• The chromosomes move to the equator of the cell
  and align to the equatorial plane.

11
ANAPHASE

• Anaphase
• Two sister chromotids separate into 2 independent
  chromosomes as the centromere divides.
• Shortening of the microtubular spindle fibers
  pulls the chromosomes in opposite directions
  toward the poles.
• At the end of the anaphase, the chromosomes lie
  in 2 groups near opposite poles of the spindle.
• Cytokinesis starts at the middle of the
  equatorial plane.

12
TELOPHASE

• During telophase
• nuclear membrane forms around each set of
  chromosomes,
• chromosomes uncoil and become less distinct and
  nucleoli are also formed
• new cell plate expands between cells.
