In the experiments conducted by Hershey and Chase, what was used to label the DNA inside the viral casing?
Understand the Problem
The question is asking which radioactive element was used to label the DNA in the experiments by Hershey and Chase. This involves understanding the principles of their experiments related to DNA and viruses.
Answer
Radioactive phosphorus-32 (P-32).
In the Hershey and Chase experiments, radioactive phosphorus-32 (P-32) was used to label the DNA inside the viral casing.
Answer for screen readers
In the Hershey and Chase experiments, radioactive phosphorus-32 (P-32) was used to label the DNA inside the viral casing.
More Information
The Hershey and Chase experiment was crucial in establishing DNA as the genetic material. Phosphorus-32 was used because phosphorus is present in DNA but not in proteins, allowing for the tracking of DNA within the bacteriophage.
Tips
Confusing the isotopes: Phosphorus-32 was for DNA, and sulfur-35 was for protein. Always match isotopes to macromolecules correctly.
