1. The Cell Cycle
Growth and Division

2. In the Nucleus Chromatin – lots of DNA, long string like strands
Sister Chromatids
Centromere
Chromosome – carry genetic material, DNA
Chromatin – lots of DNA, long string like strands

3. Spindle Fibers and Centrioles

4. Duplicates Chromosomes
Inter phase
This is the Growth part
The cell gets bigger
Prepares for Division
Busiest phase
Duplicates Chromosomes

5. Mitosis Result …to produce identical complete set of chromosomes
two “daughter” cells
identical
complete set of chromosomes

6. Prophase Happens First Chromatin Coils
Nuclear envelope starts to disappear
Chromatin Coils
Forming Chromosomes
With two identical halves Called
Sister Chromatids
That are held together in the middle by Centromeres

7. Metaphase Second The doubled Chromosomes
move to the center of the cell
centrioles are at opposite sides of the cell
spindle fibers appear

8. Anaphase Third centromeres split
sister chromatids of each chromosome pull away
…spindle fibers help

9. Telophase Last, fourth phase
Nuclear envelope reforms
chromatids move to opposite sides of the cell…2 nuclei form around each
A new cell membrane forms
to split into 2 individual cells, cytokinesis
