• Chromosomes are copied (# doubles)• Chromosomes appear as threadlike coils
(chromatin) at the start, but each chromosome and its copy(sister chromosome) change to sister chromatids at end of this phase
CELL MEMBRANENucleus
Cytoplasm
Centromere – place where the two sister chromatids meet

• Mitosis begins (cell begins to divide)• Centrioles (or poles) appear and begin to
move to opposite end of the cell. • Spindle fibers form between the poles.

• Two new nuclei form. • Chromosomes appear as chromatin
(threads rather than rods).• Mitosis ends.

• Cell membrane moves inward to create two daughter cells – each with its own nucleus with identical chromosomes.
