  1. All cells arise from pre-existing   cells
     
  2. Prokaryotes reproduce by DNA replication   followed by binary   fission.
     
  3. The complementary   nature of the DNA double helix allows for easy replication.
     
  4. Human DNA is packaged into chromosomes   composed of diploid pairs.



     
  5. Sexual reproduction involves alternation between mitosis  , which produces diploid   cells, and meiosis  , which produces haploid   cells.

     
  6. Mitosis is part of a cell cycle, which is regulated at several checkpoints   to control cell growth.


     
  7. Mitosis






     
  8. Meiosis


     
  9. Nondisjunction   may occur during meiosis, resulting in gametes with incorrect number of chromosomes.
