What might be Hershey and Chase have concluded if they had found 32P and 35S in bacterial cells?

They might have concluded that both protein and DNA transmitted hereditary material. The 32P was a radioisotope in DNA, and the 35S was a radioisotope in proteins. They were used to track the DNA and proteins to see if they were injected by a virus into a bacterium.

∙ 9y agoBoth the virus's protein coat and its DNA were injected into the bacteria.
The virus's protein coat was not injected into the bacteria.
The virus DNA was not injected into the bacteria.
Experimental error, or that the genetic material was both protein and nucleic acid.

How did Hershey and Chase's research with bacteriophages help confirm that DNA is in genetic material?
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.
What role did studying bacterial viruses play in identifying genetic material?
My biology book says: Hershey and Chase's experiment with bacteriophages confirmed Avery's results, convincing many scientists that DNA was the genetic material found in genes- not just in viruses and bacteria, but in all living cells. Hoped this helps :)
Describe the experimental design that allowed Hershey and Chase to distinguish between the two options for genetic material?
Hershey and Chase knew that the particular phage they worked with has two basic components: DNA on the inside, coated with protein on the outside. In their expt theylabelled phages with radioisotopes . For one batch of infecting phages, they used a radioactive isotope of sulfur to label only the phages' protein coats.In another batch of phages, they used a radioactive isotope of phosphorus to label only DNA. Next, they allowed each batch of phages to infect separate cultures of nonradioactive bacterial cells. They then whirled each culture in a blender to shake loose any parts of the phages that remained outside the bacterial cells. Result of expt. confirmed that only DNA of phage entered bacteria .
Who concluded that all cells came from existing cells?
Doctor Rudolf Virchow stated that all cells could form only from other cells.
Highly resistant forms of bacterial cells?
Spores are highly resistant forms of bacterial cells.
How did the Hershey and chase experiment produce evidence the DNA and not protein is the hereditary material in 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.

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.

What did Hershey and chase find through their experiment with infected bacteria?
The genetic mateial is made of DNA and not of proteins
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.
Hershey and Chase use what organism to show that DNA is the molecule that stores genetic information in living cells?
They used the T2 phage in their Blender experiment.

How did hershey and chase and chase help build our understanding of genetics?
They showed that DNA carries genetic material.
Concluded that all animals are made up of cells?
Darwin concluded that all animals are made of cells
Bacterial cells do not have a genetic material?
no, bacterial cells do not have genetic material
Do bacterial cells have a nuclues?
Bacterial cells are not eukaryotic cells, which means they do not have a nucleus. They do, however, have chromosome.
