Watson & Francis Crick Double Helix Model 1953 A Double standard helix uniform diameter two strands run in opposite direction base pairing is complementary The structure of the DNA is essential to its function Three Models for Replication Semi-conservative- Replication of cell with both original & new information Conservative - Replicated one full original cell & a new cell Dispersive Meselson & Stah's Experiment From Genotype to Phenotype - How does genetic information translate into Phenotype? From DNA to Protein - One gene – One Ezyme The central Dogma of Molecular Biology Flow of Information a) DNA ↵ → RNA → Protein b) DNA↔ RNA → Protein Two Central Questions - How does genetic information get from the nucleus to the cytoplasm? Transcript Transcription and the Messenger Hypothesis - Genetic Code - 3 letter The Code is Redundant " " not ambigous " " universal Bases - Thymine - Adenine - Cytosine - Guanine All DNA is made of the same formula but comes in different forms
