In the Hershey-Chase experiment radioactive Sulfur was used to:
- Be incorporated into the phage DNA because of its numerous sulfur atoms
- Be incorporated into the phage protein coat because of its numerous phosphorous
atoms
- Be incorporated into the phage DNA because of its numerous phosphorus atoms
- Be incorporated into the phage protein coat because some amino acids contain sulfur
Correct Answer: - Be incorporated into the phage protein coat because some amino
acids contain sulfur
The experiments by Hershey and Chase helped confirm that DNA was the hereditary
material on the basis of the finding that:
- Radioactive phage were found in the pellet
b. Radioactive cells were found in the supernatant
c. Radioactive sulfur was found inside the cell
d. Radioactive phosphorus was found inside the cell Correct Answer: d. Radioactive
phosphorus was found inside the cell
