What might hershy and chase have concluded if they had found 35s instead of 35p in bacterial cells? Explain your answer
kaheart [24]

Hershey and chase have concluded that DNA is not protein it was the genetic material.

Explanation:

The internal DNA is not a protein, a genetic material. They used label to find it. The lack of 32p labeled DNA remaining in solution after bacteriohages are allowed to absorb the bacteria showed tha DNA was transferred into the bacterial cell.

The radioactive 35s in the solution shows that protein coat protects the DNA before adsorption.
