MITOSIS FLIP BOOK
ALEXIS TUCKER
EARLY PROPHASE
The nuclear membrane and the nucleolus start to disappear. The spindle fibers start to form.
LATE PROPHASE
The nucleus has completely disappeared. The spindle fibres have fully formed, and they attach themselves to the
centromeres.
METAPHASE
The spindle fibres tug the X shaped chromosomes into a line across the middle of the
cell.
ANAPHASE
The spindle fibres begin to contract and shorten which pulls the centromere apart to let the sister chromatids
move to the opposite sides of the cell. Once they separate, each chromatid is a chromosome.
TELOPHASE
The spindle fibres begin to disappear, and a nuclear membrane forms around the chromosomes.
A nucleolus appears within each nucleus. There are two nuclei in the cell, now it’s about to divide.
CYTOKINESIS
This is the final stage in mitosis. Cytokinesis separates the nuclei into two daughter cells which are
identical to the original cell.
