Cellular division Mitosis - exact duplication of nuclear material; 0. Two daughter cells are identical to parent. Cells life cycle 5 phases IPMAT interphase, prophase, metaphase, anaphase, telophase Interphase - 3 parts G1- normal growth and development S- where chromosomes replicate*** G2- cell readies for division Chromosome duplication When chromosomes duplicate, Copies remain attached at the centromere Each copy is called a chromatid . Mitosis phases 1) Prophase 2) Metaphase 3) Anaphase 4) Telophase Prophase: 1) Chromosomes shorten and thicken

Unformatted text preview: 2) Nuclear envelope disappears 3) Mitotic spindle fibers appear 4) Centrioles migrate to opposite poles Metaphase Chromosomes line up on equatorial plane . Anaphase Sister chromatids are pulled apart by the shortening of the spindle fibers. Once the chromatids are separated, They are now considered individual chromosomes. Telophase Nuclear material thins out. Nuclear envelope reappears . Cytokinesis Cytokinesis begins at the end of anaphase and continues through telophase. Cleavage furrow- animal cells...
