  4. 11. Complete collection of that organisms genetic information.
  5. 12. 46______ that is the same in function and size.
  6. 13. Reproduction carried out by prokaryotic cells in which the chromosomes replicate and cell pinches between the attachment points of the 2 resulting chromosomes to form 2 new cells.
