Question

Hershey and Chase demonstrated that DNA and protein enters the bacterial cell during phage reproduction and both are passed onto progeny cells.

a. True
b. False

Answer 1

Hershey and Chase's experiments showed that DNA, not protein, enters the bacterial cell during phage reproduction and is passed on to progeny cells.

Step-by-step explanation:

Hershey and Chase's experiments showed that DNA, not protein, enters the bacterial cell during phage reproduction and is passed on to progeny cells. They conducted an experiment using bacteriophages labeled with radioactive sulfur (35S) to label the protein coat and radioactive phosphorus (32P) to label the DNA. The results showed that only the 32P labeled DNA entered the bacterial cells, proving that DNA is the genetic material.
