  1. History of Genetics/INTRO TO DNA

  2. (1) Gregor Mendel“The Father of Genetics” • A Monk: Studied pea plants in in a garden • Discovered dominant and recessive traits http://www.nlm.nih.gov/visibleproofs/galleries/technologies/dna.html

  3. (2) Rosalind Franklin • Created images of the DNA molecule that showed its spiral shape. http://profiles.nlm.nih.gov/KR/B/B/J/N/ http://www.accessexcellence.org/RC/AB/WYW/wkbooks/SFTS/SFTSg/1.jpg

  4. (3) James Watson & Francis Crick • These two scientists discovered the complete structure of DNA • “The Double Helix” http://www.achievement.org/autodoc/photocredit/achievers/wat0-001

  5. The Structure of DNA

  6. (4) Shape • DNA has a double helix shape • If you took a ladder and twisted it, it would look like DNA Helix = Spiral

  7. Composition

  8. (5) 1. DNA is made up of phosphates, sugars, and bases (purines and pyrimidines)

  9. (5) 2. A nucleotide is made up of 1 sugar, 1 phosphate and 1 base(Circle a nucleotide on your paper!)

  10. A Nucleotide PHOSPHATE BASE SUGAR

  11. (5) 3. The nucleotides are connected together by the phosphate and the sugar(Think: Sugars and Phosphates= “Side Poles” of the Ladder)

  12. "Side Poles“ "Side Poles" Sugar and Phosphate "Side Poles“

  13. A T G G

  14. “Between “ Bases “Between “

  15. (5) 4. • When the bases pair together, they form a DoubleHelix.
