1. AIM: What are the phases of the Cell Cycle?
I. What happens during Interphase?
Cell
Cell

2. Interphase:
DNA (chromosomes)
are replicated.
Centromere
Chromatid

3. Interphase
Centrioles
The organelles for cell division are produced.

4. II. “M” Phase = MITOSIS -the cells undergo cell division.
“The dance of the
Chromosomes”

5. III. Stages of Mitosis: Prophase: The chromosomes become visible.
The centrioles separate and
Spindle fibers begin to form.
The nuclear membrane breaks
down.
Centriole
Nuclear
Membrane
Spindle Fibers

6. Stages of Mitosis: Metaphase: The chromosomes line up
across the center of the cell.
Each chromosome is connected to
a spindle fiber at the centromere.

7. Stages of Mitosis: Anaphase: The spindle fibers separate
the chromatids into individual
chromosomes and they
are moved apart.

8. Stages of Mitosis: Telophase: The chromosomes gather at
opposite ends of the cell.
2) Two new nuclear membranes form.
The chromosomes lose their
distinct shapes.

9. Cytokinesis:
The cytoplasm pinches and
two cells are formed.

10. What is the end result of Mitosis?
46X
46X
46X +
Daughter Cell
Daughter Cell
Parent
Is the genetic material of the
daughter cells identical to the
parent?
Chromosome Number?
The same number of
chromosomes is maintained
from one generation to the
next.
