Question 1

What is Alfred Hershey's significance in genetics?

Accepted Answer

Alfred Hershey is significant in genetics for his groundbreaking work on bacteriophages, particularly his role in the Hershey-Chase experiment, which helped establish DNA as the carrier of genetic information. This discovery was crucial for the development of molecular genetics and understanding how genetic information is inherited.

Question 2

What was the Hershey-Chase experiment?

Accepted Answer

The Hershey-Chase experiment, conducted in 1952 by Alfred Hershey and Martha Chase, used a T2 bacteriophage to demonstrate that DNA, and not protein, is the genetic material of viruses. They used radioactive labeling to trace which part of the virus, DNA or protein, entered the host bacterial cell during infection and found that only the DNA entered, proving it carried genetic information.

Question 3

When did Alfred Hershey win the Nobel Prize?

Accepted Answer

Alfred Hershey was awarded the Nobel Prize in Physiology or Medicine in 1969, along with Max Delbrück and Salvador Luria, for their discoveries about the replication of viruses and the genetic structure of viruses.

Question 4

Who was Alfred Hershey?

Accepted Answer

Alfred Hershey was an American bacteriologist and geneticist known for his experiments that demonstrated that DNA is the genetic material of viruses and ultimately of all living cells. He was awarded the Nobel Prize in Physiology or Medicine in 1969 for his contributions to the understanding of the genetic structure of viruses.
