  6. Gene • instructions for traits • sections of DNA on chromosomes • found in pairs • have specific locations on chromosome

  7. DNA • deoxyribonucleic acid • long strands that make up genes (instructions)

  8. Robert Hooke Anton Van Leeuwenhoek Robert Brown Used microscope to view samples of cork Gave “cells” their name First to see living organisms Gave the name “nucleus” to the dark blob seen in cells.

  9. Draw and label the parts of a cell… Chromosomes Nucleus Gene Pair DNA Cell
