Chromatin has not yet thickened. Chroamtin has thickened into visible chromosomes. Nucleoli and nuclear membrane disintegrate. Kinetochore fibers form to align chromosomes along the equator of the cell. Chromatids separate and migrate towards the cell poles due to combined action of kinetochore and polar fibers.
Chromatids cluster at the poles and fibers disappear.
Chromatids unwind, nuclear membrane forms and nucleoli appear. Freshman Nick Burger is a member of WVHS Student Council and is particularly interested in mathematics. Rebecca Mease, Class of 1998, is highly interested in genetics and microbiology.
