Controls the activities of the cell Controls the activities of the cell Holds the genetic material (DNA) Holds the genetic material (DNA) Contains genes (made of DNA) on 46 chromosomes. Thousands of strands of DNA can fit onto one chromosome. These have all the instructions for your body. http://www.cartage.org.lb/en/themes/Sciences/Zoology/ AnimalPhysiology/Anatomy/AnimalCellStructure/Nucleus/ cellnucleus.jpg
