If a mixture of bacteriophages, some labeled with radioactive sulfur and others labeled with radioactive phosphorus, is placed in a bacterial culture, the bacteria will eventually contain:
1. Radioactive sulfur
2. Radioactive phosphorus
3. Both radioactive sulfur and phosphorus
4. Neither radioactive sulfur nor radioactive phosphorus
5. Complete viruses with radioactive sulfur coats.
( I believe it is #3, but want someone to back me up on this. Thanks!)
