DNA is the genetic material. However, Hershey-Chase also stated that some little sulfur containing material also entered the bacterial cell. Looking at these two conclusions, Hershey-Chase could not reach a definite conclusion as to whether DNA or Protein contains the genetic material. The conclusion came from Watson-Crick who stated that the sulfur containing material could have entered the cell due to the fact that DNA replication and subsequently translation of the mRNA leads to the synthesis of sulfur containing protein which were found in the bacterial cell.

∙ 13y agoHershey and Chase showed that the genetic material of the t2 bacteriophage is DNA.
They wanted to see whether viruses injected their DNA or a special protein coat into harmless bacteria, causing the bacteria to produce more viruses. First, they put a radioactive tracer on the protein and the DNA, and then they let the bacteriophage (virus) infect a harmless bacterium.
They then looked to see which radioactive marker showed up in the bacterium. They found out that it was the DNA that showed up, proving that the factor that allowed the bacteriophage to re-copy itself within the bacterium was DNA and not protein.

Who concluded that the genetis material of a bacteriophage is DNA?
The scientists Alfred Hershey and Martha Chase conducted a series of experiments at the Carnegie Institute of Washington in 1952, and concluded that the genetic material of a bacteriophage was DNA.
Describe the contributions of hershey and chase to the understanding that DNA is the genetic material?
Hershey and Chase radioactively labelled T2 bacteriophage with P (DNA) and S (protein) to determine if protein or DNA carried the genetic material. They let the bacteriophage infect E.coli. The radioactive material found in the host E.coli contained the radioactive P (found in DNA) as the bacteriophage had multiplied inside the cell, but the radioactive S was not found inside the cell. Therefore DNA is the hereditary molecule resorce - some other guy off the internet
What did Hershey and chase show about genetics?
In their experiments, Hershey and Chase injected chemical tracers that resembled proteins and DNA into a type of rapidly reproducing virus called T2. They then tracked the course of the tracers as they made their way through reproduction and found that the tracers that resembled DNA were much more likely than the tracers that resembled proteins to be found in future generations of the cells. Hershey and Chase concluded that DNA, and not protein, was associated with genetic material.
How did the Hershey and Chase experiment produce evidence that DNA and not protein is the hereditary material and viruses?
They found that all of the viral DNA and little of the protein had entered E. coli cells. Then they concluded that DNA is the hereditary molecule in viruses.
Who was the first person to declare DNA to be the genetic material?
In 1928, Frederick Griffith was able to transform harmless bacteria into virulent pathogens with an extract that Oswald Avery proved, in 1944, to be DNA. In 1952, Martha Chase and Alfred Hershey used radioactively labeled virus DNA to infect bacteria, proving the same point.

Why was Alfred Hershey and Martha Chase's experiment so important?
In their experiments, Hershey and Chase showed that when bacteriophages, which are composed of DNA and protein, infect bacteria, their DNA enters the host bacterial cell, but most of their protein does not. Although the results were not conclusive, and Hershey and Chase were cautious in their interpretation, previous, contemporaneous and subsequent discoveries all served to prove that DNA is the hereditary material.
What did the hershey-chase blender experiment help prove?
The genetic material is made of DNA.
What summarizes the findings of Hershey and Chase?
Alfred Hershey and Margaret Chase confirmed that DNA is a genetic material.
