Definition
| Experiment that relied on a chemical difference between DNA and protein. In DNA, phosphorus is present but sulfur is not, and in protein, sulfur is present but phosphorus is not. |

Term
|
Definition
• Was an expert in x-ray crystallography
• Used this technique to examine DNA
• Concluded that DNA was some sort of helix
• Phosphate bonds were on the outside of the molecule |
|
|
Term
|
Definition
• DNA consists of two nucleotide strands – Molecule is a double helix
• Strands run in opposite directions – antiparallel
• Strands are held together by hydrogen bonds between bases |
|

Definition
| DNA strands run in opposite directions |

Term
| semiconservative replication |
|
Definition
| duplication of DNA resulting in two double helix molecules, each having one parental and one new strand. |
|
|
Term
|
Definition
• Each parent strand remains intact
• Every DNA molecule is half “old” and half “new” |
