light microscope as chromosomes. The nucleolus disappears.
Centrioles begin moving to opposite
ends of the cell and fibers extendfrom the centromeres.
Some fibers cross the cell to form
the mitotic spindle.
Metaphase Proteins attach to the centromeres
creating the inetochores.
Microtubules attach at the
inetochores and the chromosomes
begin moving. Spindle fibers align the
chromosomes along the middle of
the cell nucleus. This line is referredto as the metaphase plate. This
organi!ation helps to ensure that in
the next phase" when the
chromosomes are separated" eachnew nucleus will receive one cop#
of each chromosome.
Anaphase The paired chromosomes separate
at the inetochores and move to
opposite sides of the cell. Motionresults from a combination of
inetochore movement along the
spindle microtubules and throughthe ph#sical interaction of polar
microtubules.
Telophase Chromatids arrive at opposite poles
of cell" and new membranes form
around the daughter nuclei. The
chromosomes disperse and are nolonger visible under the light
microscope. The spindle fibers
disperse" and c#toinesis or the
partitioning of the cell ma# alsobegin during this stage
C#toinesis $n animal cells" c#toinesis results
when a fiber ring composed of a
protein called actin around thecenter of the cell contracts pinching
the cell into two daughter cells"
each with one nucleus. $n plantcells" the rigid wall re%uires that a
cell plate be s#nthesi!ed between
the two daughter cells.
