Observation and Conclusions

Explanation

### Step-by-Step Solution:

**Introduction:**
Hershey and Chase conducted an experiment in 1952 to determine whether DNA or protein was the hereditary material in viruses. They used bacteriophages, which are viruses that infect bacteria, to carry out their investigation.

**Step 1: Selection of Bacteriophage**
- Hershey and Chase chose the T2 bacteriophage, which infects Escherichia coli (E. coli) bacteria. This choice was crucial as it allowed them to track the genetic material that entered the bacterial cells.
