  1. 10.2 The Process of Cell Division p279

  2. Q: What is the role of chromosomes in cell division? A: Chromosomes make it possible to separate DNA precisely during cell division.

  3. In prokaryotes: not in nucleus Circular (plasmid) In Eukaryotes: several chromosomes Often X shaped Chromosomes-contains the genetic information (DNA)

  4. Chromatin-DNA coiled around histone

  5. Prokaryotes DNA duplicates Membrane indents Cell forms 2 identical The Cell Cycle-growth, prepares for division & divides to form 2 daughter cells

  6. Interphase G1-Cell growth S-DNA replication G2-Prepare for mitosis Largest amount of cell life in this part (Interphase). Eukaryotes-2 parts: Interphase & Cell Division

  7. M Phase or Mitosis & Cytokinesis PMAT=Mitosis • Prophase- genetic material condenses (X), chromosome visible, spindle forms. Centromere-center of chromosome Centriole-animals; helps cell divide.

  8. 2. Metaphase- chromosomes (X) line up in the middle of the cell. Centrioles opposite ends.

  9. 3. Anaphase-chromosomes separate at the centromere & move to opposite ends.

  10. 4. Telophase- Nuclear envelope re-forms around chromosomes.

  11. Cytokinesis- Division of the cytoplasm. Cell plate forms in plants. Plant Cells Animal Cells
