1 MOLECULAR GENETICS DNA & RNA

2 A Brief Look at History Key figures: Leverne Griffith
Avery, MacCleod, McCarty Hershey, Chase Chargaff Franklin Watson and Crick

3 How does DNA really look? - Time line

4 Double Helix “twisted ladder” Handrails are sugar-phosphate backbone
Five carbon sugar Phosphate group Rungs are the nucleotides One of five nitrogen-containing bases Adenine (A), Thymine (T), Cytosine (C), Guanine (G) and RNA has Uracil (U).
