interphase
longest portion of the cell cycle
interphase
consists of G1, S, and G2 phases
prophase
nuclear membrane starts to disintegrate
prophase
nucleoli disappear
prophase
pairs of centrioles migrate toward opposite poles of cell
prophase
chromatin in the nucleus condense into thick, rod-shaped chromosomes
prometaphase
chromosomes migrate toward the center of the cell as pairs of chromatids
prometaphase
microtubules form spindle apparatus
metaphase
chromosomes line up randomly along a metaphase plate at the center of the cell with one chromatid located on each side of the cell's equator
anaphase
centromeres split and microtubules pull identical chromatids apart
anaphase
chromatids migrate toward opposite poles of the cell as they become daughter chromosomes
telophase
the spindle apparatus is disassembled
telophase
daughter chromosomes decondense and form a tangled mass of chromatin
telophase
new nuclear envelope forms around each tangled mass of chromatin
telophase
nucleoli reappear
