Question

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

Answer 1

They would have concluded that the protein coat also entered the bacterial cell and could not deduce that protein is the genetic material.

Explanation:

In their experiment, Hershey and chase found that all the DNA coated with 32 p were missing from the solution as bacteriophage after adsorption on bacterial cell their DNA was transferred to the bacterial cell. The presence of 32 S in the solution shows that the protein coat does not enter the cell during infection.

This way they concluded that DNA is the genetic material and not the protein.

Since phage infecting bacteria inserted their DNA into it and got replicated increasing their number. Also, protein is not involved in their growing numbers.

Answer 2

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

Explanation:

Hershey and chase said that DNA is not protein it was the genetic material. They took a direct physical approach in finding the genetic material. They both determined that a protective coat was formed around the bacteriophage.

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.
