Stages of Mitosis

Question	Answer
INTERPHASE [LATE G2 PHASE] Image: Picture4 (binary/octet-stream)	1) DNA and some organelles are copied 2) Allow 2 homologous chromatids to pair and form sister (identical) chromatids
EARLY PROPHASE Image: Picture1 (binary/octet-stream)	1) Chromosomes start to condense 2) Mitotic spindle begins to form 3) Chromosomes condense into X pairs 4) Cell organelles begin to split -> move to opposite side of cells 5) Nuclear envelope begins to break down
LATE PROPHASE [PROMETAPHASE] Image: Picture5 (binary/octet-stream)	1) Nuclear envelope beaks down completely 2) Spindle fibers are fully developed 3) Spindles begin to sort chromosomes by attaching their centromeres 4) Kinetochore develops
METAPHASE Image: Picture7 (binary/octet-stream)	1) Nuclear membrane breaks apart 2) Spindles attach to sister chromatids 3) Chromosomes line up at center of cell (metaphase plate)
ANAPHASE Image: Picture6 (binary/octet-stream)	1) Spindle fibers shorten 2) Pairs of chromosomes are now at each side of the cell
TELOPHASE Image: Picture8 (binary/octet-stream)	1) At each pole, full set of chromosomes gather 2) Membrane forms around each set of chromosomes to create two new nuclei
CYTOKINESIS Image: Picture9 (binary/octet-stream)	1) Single cell then pinches in the middle to form two separate, identical daughter cells 2) There is now a full set of chromosomes in each nucleus
