mitosis
Chromosomes are duplicated during this phase. the resulting sister chromatids are held together at the centromere. the centrosomes are also duplicated
S phase
Chromosomes condense and spindle fibers start to form
Prophase II
the nucleus and the envelope are distinct and the chromosomes are in the form of threadlike chromatin
Interphase
spindle fibers attach to the chromosomes. the chromosomes are lined up at the equator of the cell, at a point known as metaphase plate
metaphase II
thick coiled chromosomes, each with two chromatids, are lined up at the center of the equator
metaphase
The cell separates as the sister chromatids are pulled apart by spindle fibers
anaphase II
the chromatids of each chromosome have separated and are moving toward the poles
anaphase
Two new nucleus form from each haploid cell. the spindle fibers break down. The gametes separate from each other through a process known as cytokinesis
Telophase II
the spindle dissolves and nuclear envelopes form around the chromosomes in both cells
telaphase
