Why can't
Chromosomes?
wrapped up/ compiled DNA
- made of DNA and proteins.

- 3 pairs of chromosomes
- 2n = 6
G1 phase
- protein synthesis
- takes about 10 hrs.
G2 Phase
preparation for mitosis.
needs more proteins to mitosis to go.
centrosomes make their way to the north and south pole.
S phase
(DNA synthesis)
- DNA is copied before cell division.
- centrosomes are replicated.
Mitosis
Goals:
Separate replicated DNA
Move them to opposite sides of the cell
Form new cells around them
Prophase 1
chromatin / DNA coils up into chromosomes.
spindle fibers spread to
Prometaphase
