Interphase
Interphase - includes G1, S, and G2
So we just draw a basic cell to start with
Interphase
Interphase G1
G1 (Gap 1): Cell grows and continues
with normal functions. It duplicates
organelles. It prepares everything
needed for DNA replication. One
centriole is present from the last
division. DNA is "unpacked" in threadlike form called chromatin.
Interphase G1
Cell spends 95% of its’ time in
this phase
Cell is performing typical
metabolic functions in this
phase
At the end of this phase, the
cell prepares to duplicate its’
organelles
Interphase G1
G1 (Gap 1): Cell grows and continues with normal functions. It duplicates organelles. It
prepares everything needed for DNA replication. One centriole is present from the last
division. DNA is "unpacked" in thread-like form called chromatin.
Interphase S
S (Synthesis):
Cell replicates all
DNA
Interphase S
Interphase S
Prophase
Prophase - Chromotid pairs join
to form chromosomes (two
identical chromatids attached
by a centromere). The nuclear
membrane breaks
down. Centrioles move toward
opposite ends (poles) of the
cell
Prophase
Metaphase
Metaphase - Chromosomes line up in the middle (equator) of the
cell. Spindle fibers from the centrioles attach to the centromeres
of every chromosome
Anaphase
Anaphase - Chromatids of each chromosome split and are pulled by spindle fibers to
opposite ends (poles) of the cell.
Telophase & Cytokenisis
Telophase - The cells begin to pinch and new nuclear membranes form.
OK, Guys, time to
get ready to
synthesize more
organelles
Gotta eat, Gonna
make
It’s finally
time to
become a
butterfly!
Ow!
Stupid
Caterpillar
I’m so proud!
I’m about to
have a
daughter
Do these chromosomes
make me look fat?
Eww! There’s
a mutated
cell behind
me!
What nice
spindles you
have.
OK guys,
time to
move those
centrioles!
I’ve got a
major
pain right
down the
middle of
me
Come on
guys, PULL!
Now we need to
move our
membrane
We did it!
We get one
too, don’t we?
Just a bit more
membrane, and we’ll
be done.
Which one
of you is my
daughter?
We are!
And that my friends,
Is THE END
(or just the beginning)
