How did Hershey and Chase established that DNA is transferred from virus to bacteria?

Explanation

**Step-by-Step Solution:**

1. **Introduction to Hershey and Chase Experiment:**
- Hershey and Chase aimed to determine whether DNA or protein was the genetic material transferred from viruses to bacteria. They used bacteriophages, which are viruses that infect bacteria, for their experiments.

2. **Use of Radioactive Isotopes:**
- They labeled the proteins of the bacteriophage with radioactive sulfur (S-35) and the DNA with radioactive phosphorus (P-32). This allowed them to track which component was transferred into the bacteria during infection.
