DNA Experiments

DNA? Protein? RNA? The Big Question… What is the genetic material that gets passed on? DNA? Protein? RNA?

The Experiments - Griffiths Experiment (Mice & Bacteria) - Hershey/Chase Experiment (Viruses & Bacteria) Chargaff’s Experiment Rosalind Franklins X-ray diffraction

Griffiths Experiments Can DNA transform bacteria?

Hershey/Chase Experiment

Radiolabeling and Isotopic Markers Techniques used to label protein and DNA so that their movements can be traced/followed

Chargaff’s Experiments Analyzed ratios of bases...
