cell cycle

• Chromosome

  Coils of DNA containing genes
• There are 23 pairs of chromosomes in each body cell, and 23 in each sex cell
• Cell cycle and mitosis

  1. Interphase: cell grows, organelles increase, DNA replicates

  2. Mitosis: chromosomes line up and are pulled to opposite sides

  3. Cytokinesis: cytoplasm and cell membranes divide to form two daughter cells
• Mitosis

  • Important for growth, development, replacing damaged cells, and asexual reproduction
