What did Hershey and chase attach radioactive sulfur to?
bunny versus pie
What radioactive isotope did hershey and chase use to tag phage DNA?
phosphorus - 32P
In 1952 hershey and chase used a bacteriophageto determine that genetic material is made of what?
These two isotopes are: phosphorus-32 and sulfur-35.
Why did Hersheys and chase grow viruses in cultures that contained both radioactive phosphorus and radioactive sulfur?
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.
Worked with radioactive isotopes and to identify genetic material?
Hershey and chase
What scientists carried out experiments using radioactive tags?
Hershey and Chase
Which radioactive tracer showed up in the bacteria that led Hershey and Chase to their conclusion that DNA not Protein was the genetic material?
According to my bio book, I think it's Alfred Hershey and Martha Chase, in the HERSHEY-CHASE experiment.
What did hershey and chase observe in the offspring bacteria?
Hershey and Chase observed that DNA is the identity of the hereditary material in phage T2. Hershey and Chase used radioactive labels to mark the protein of the bacteriaphage in one experiment and the DNA in another.

What two radio active elements did Hershey and Chanse inject into bacteriophages?
Hershey and Chase used isotopes of sulphur and phosphorus. Please see the link.
What researchers used radioactive markers in experiments to show that DNA was the genetic materials in cell?
According to my bio book, I think it's Alfred Hershey and Martha Chase, in the HERSHEY-CHASE experiment.
Why did Hershey and Chase grow viruses in cultures that contained both radioactive Sulfur. What might have happened if they had used only one radioactive substance.?
Radioactive sulfur and phosphorous. Proteins contain sulfur, but no phosphorous. Nucleic acids contain phosphorous, but no sulfur. The T even phages they used were nucleic acid enclosed in a capsid of protein. So, to label them radioactively told them by experiment which substance, nucleic acid or protein, was the generic material. To only use one radioactive substance would have been useless in telling which was the genetic material. Google Hersey and Chase for more detail.
