Question

If the Hershey and Chase experiments had shown radioactive sulfur in the infected bacteria, this would have confirmed the Avery and Macleod experiments.

Select one:
a. TRUE
b. FALSE

Answer 1

The Hershey and Chase experiments used radioactive sulfur and phosphorus to label bacteriophages. If radioactive sulfur had been found in the infected bacteria, it would have confirmed the Avery and MacLeod experiments. However, the experiments showed that only radioactive phosphorus.

Step-by-step explanation:

The Hershey and Chase experiments used radioactive sulfur and phosphorus to label bacteriophages. The use of radioactive sulfur and phosphorus allowed Hershey and Chase to track the movement of these elements in the infected bacteria. If radioactive sulfur had been found in the infected bacteria, it would have confirmed the Avery and MacLeod experiments, which showed that DNA is the genetic material. However, the Hershey and Chase experiments showed that only 32P, the radioactive phosphorus, entered the bacterial cells, indicating that DNA is the genetic material.
