mr. w (rap) - the mitosis rap lyrics

(intro):
guys, i want everyone’s attention
we’re gonna go over what we did yesterday
we’re gonna go over the stages of mitosis
alright, everybody ready? alright, let’s go!

(verse 1-interphase):
interphase is cell division’s longest part
nuclear membrane’s intact as it starts
the cells growin’, cytoplasm flowin’
chromosomes get duplicated, dna get’s replicated
chromosomes are spread out so they can’t be seen distinctly
but note the nucleolus, the ribosome factory
outside the nucleolus are two centrosomes
they later make a spindle, which will pull apart the chromosomes
prophase follows, the chromosomes condense
each is made of 2 chromatids, like an, “x”
each sister is a clone, the closest of kin
and a centromere connects them like siamese twins
the nucleolus disappears, it melts away
as a cell takes a ribosome production holiday
the centrosomes separate, start spindle formation
for separating chromatids and cell elongation

(chorus):
mitosis, chromosomal ride
inter-, pro-, meta- ana-, telophase, divide!
eukaryotes go from one cell to two
mitosis; how cells renew

(verse 2-pro/metaphase):
in late prophase, prometaphase
the nuclear membrane disintegrates
the centrosomes migrate to the cell’s opposing sides
and between them the fibers of them spin and wend and wind
the spindle’s made of microtubule fibers which attach
to chromosomes at kinetoch0r-s a protein patch
that serves like a handle that the fibers can grasp
when they pull apart the chromosomes, splitting them in half
the spindle moves the chromosomes with nudges so fine
into linear formation on the 50-yard line
a location equatorial defining metaphase
where the chromosomes are lined up in that middle place

(chorus):
mitosis, chromosomal ride
inter-, pro-, meta- ana-, telophase, divide!
eukaryotes go from one cell to two
mitosis; how cells renew

(verse 3-anaphase):
the spindle fibers pull on the kinetoch0r-s
a cellular, molecular, mitotic tug of war
the centromere snaps, sisters get separated
now these chromatids are chromosomes, they’ve been upgraded!
the snapping separation defines anaphase
the, “a” for “apartness” for moving different ways
kinetoch0r- spindle fibers separate the sisters
see ’em waving goodbye, calling out, “i’m gonna miss ya!”
and the other spindle fibers push and grapple like felons
make the cell elliptical like a watermelon (melon, melon)
in telophase the membranes form round the chromosomes
that spread out as the nucleoli come on home

(chorus):
mitosis, chromosomal ride
inter-, pro-, meta- ana-, telophase, divide!
eukaryotes go from one cell to two
mitosis; how cells renew

(final verse-telophase/plant cell mitosis):
in animal cells, there’s a ring of microfilaments
that form at the equator, and they cinch themselves in
tighter, tighter, tighter, tighter till the cell is in two pieces
yeah, in animals, that’s cytokinesis
but it’s different in plants, in them cells divide
by building a new cell wall from the inside
as the golgi sends vesicles with cellulolytic goo
which makes a plate, then a wall which divides the cell in two
and instead of one mother cell, we now have daughters two
identical twins, kind of old and kind of new
from your single celled beginning this is how you grew
and for single-celled eukaryotes, it’s reproductive, too!

(chorus 2x, outro):
mitosis, chromosomal ride
inter-, pro-, meta- ana-, telophase, divide!
eukaryotes go from one cell to two
mitosis; how cells renew

mitosis, chromosomal ride
inter-, pro-, meta- ana-, telophase, divide!
(ok guys)
eukaryotes go from one cell to two
(alright)
mitosis; how cells renew
