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.
What reaction is used to radioactivley label DNA?
DNA is labeled a radioactive phosphorus because when Alfred looked at the examples 32p always pelleted with bacteria but the new Phage made by these infected bacteria contained Radioactive 32p which is why its labeled Radioactive phosphorus.
what is a copy of DNA that is used to direct the synthesis of a specific protein?
A gene is a segment of DNA that is used to direct the synthesis of a specific protein.
What is a following reactions that is used to radioactively label DNA?
Synthesis of new DNA.
What of the following reactions is used to radioactively label DNA?
Geiger Counter! DNA polymerase (apex)
What is the Radioactive molecule used to label proteins?
Proteins are labeled with radioactive amino acids so that they can be identified. Scientists use radioactivity to label proteins in order to track them during their experiments, you can follow protein degradation, label proteins that don't have antibodies, label all proteins produced at a certain time, separate proteins produced by intracellular pathogens from host proteins, among many other uses.

In their experiments Hershey and chase put special atoms call Into the DNA and protein of viruses?
Markers :)
What is the bacteriophage used by hershy and chase consisted of two types of molecules?
protein and DNA
What can be used to radioactively label DNA?
Synthesis of new DNA

What results of OT Avery's experiments indicated that genes were not special types of protein molecules?
bacteriophages injected DNA into cells to replicate instead of protein

What is a following reactions that is used to radioactively label DNA?
Synthesis of new DNA.
In their experiments Hershey and Chase put special atoms called what into the DNA and protein of viruses?
Markers-Nova Net
Why did the scientists use radioactive sulfur and phosphorus in this experiment?
Phosphorous 32 was used to label the Nucleic Acid. Sulfur 35 was used to label the protein. The progeny of the E. coli cells Hershey and Chase grew the virus in had Phosphorous 32 in them which concluded that the DNA went inside and was the genetic material. The phage coating left on the outside tested positive for Sulfur 35 which meant protein was left on the outside.
