Mitosis Chicken Dance
Ch. 12
By PV from Mr. Peevyhouse
When you were a little babe
In your mother’s cozy womb
You were really good at math.
You divided every day
In a special kind of way
Cells began another path.
DNA in all your cells
Is identical as well
Different genes will get expressed.
Chromatin condenses down
Into chromosomes it’s wound
Mitosis yeah.
Chorus
Mitosis starts with Interphase now
G1’s the first gap with cell growth
S phase will copy DNA then
G2 will grow still ‘till it’s all done.
Verse
At the end of Interphase
Nucleus is still intact
DNA is chromatin.
Centrosomes will then appear
Centrioles within a sphere
Made of microtubules.
Then we go to the Prophase
Centrioles go separate ways
Nucleoli disappear.
Spindle fibers start to form
Chromatin starts to transform
To chromosomes.
Chorus
Mitotic Phase of the cell cycle
Accounts for ten percent of it
Most normal cells are in G0
They are not ready to go and split. / Verse
Next we have Prometaphase
Where the chromosomes condense
Each has kinetochores.
Nucleus will disappear
Chromosomes with centromere
Centrosomes move to the poles.
Once the chromosomes arrive
At the center of the cell
That will mark the Metaphase.
Centrosomes are at the poles
Microtubules attach
To the sister chromatids.
Chorus
Mitosis starts with Interphase now
G1’s the first gap with cell growth
S phase will copy DNA then
G2 will grow still ‘till it’s all done.
Verse
Sister chromatids are split
And they move to separate poles
During Anaphase that’s next.
Kinetochores move down the line
Motor molecules combine
With the spindle fibers now.
Telophase is next to come
Nuclei will start to form
Chromosomes will de-condense
The cell will then be split in two
Cleavage furrows take their cue
And we’re all done.
Chorus
Mitotic Phase of the cell cycle
Accounts for ten percent of it
Most normal cell are in G0
They are not ready to go and split.
