The Cell Cycle

The parent cell duplicates its DNA (an extra copy of each chromosome) to produce 2 identical daughter cells. G 1 S G 2 M

c) Stages of Mitosis: P M A T (and Cytokinesis) Telophase & Cytokinesis Prophase Metaphase Anaphase • Nuclear membrane disappears • Chromosomes line up across the middle of cell • Spindle fibers pull double-stranded chromosomes apart • Spindle fibers from centrioles attach to middle of the chromosomes • Single-stranded • Cytokinesis: chromosomes cytoplasm divides to move to opposite form two identical sides of cell daughter cells • Double-stranded chromosomes become visible • Centrioles move to opposite sides • New nuclear membranes form around each set of chromosomes

CYTOKINESIS 1. Animal Cell: Cell membrane squeezes together & cytoplasm pinches into 2 cells 2. Plant Cells: Form a cell plate that divides the cytoplasm and builds new cell walls to separate daughter cells. C ell
