DNA Replication
- How do we know to look @ DNA?
- 1. Griffith (Transformation)
Upshot: Some transferrable
genetic information (transformation)
- Mice infected with
streptococcus bacteria,
some transfer of material
that allowed the organism
to be infected.

- 2. Hershey and Chase (bacteriophages)
Upshot: Confirmed that DNA was said
material
- The debate for this genetic blueprint was up
between DNA/RNA/Protein. Hershey and
Chase used bacteriophages which have a
protein casing and DNA within to determine
which was passed on. The protein was tagged
with radioactive sulfur because it is in the
structure of proteins, and the DNA was tagged
with radioactive Phosphorous because it has
phosphorus in tis structure. When DNA tagged
cell was radioactive, when protein tagged cell
wasn't radioactive.

- Nucleotide Monomer
- Semi-Conservative Replication
- Chargaff:
- What is the DNA replication mechanism?
