Give an account of the Hershey and Chase experiment. What did it conclusive prove? If both DNA and proteins contained phosphorus and sulfur do you think results would have been the same?

Explanation

Solution

To confirm the DNA is a genetic material the Hersey and Chase performed the experiment while the time when many scientists still assumed at the time that proteins carried the information for inheritance in the new organisms.

Complete answer:
In the experiment both the scientists used the bacteriophage which are composed of DNA and proteins, infected bacteria are inserted into the host bacterial cell walls but after the experiment not get desired results. DNA is a hereditary material after the subsequent discoveries and interpretation all serve to prove. And in 1969 Hershey shared the Nobel Prize in Physiology and Medicine with the Scientist Max.

In the experiment Hershey and Chase examined the different phages and isolated the phages in the subsection. The labelling of each different element is called an isotope obtained from the viruses that are composed from the protein shell and DNA and both are analyzed differently. Phosphorus not containing amino acid but containing DNA, T-2 phage is labelled by using the radioactive phosphorus-32. After that kept the media growing for 4 hours. And obtained the progeny from the infected bacteriophage bacteria that contained radioactive isotopes structure. In this sulfur labelled phages and once for phosphorus labelled phages are used. And after the final concluded results the DNase is protected by the DNA. And proved DNA is the source of genetic material not the RNA.

Note: After all the conclusion the protein was not likely to be genetic material of the hereditary and not concluded the result of specific function of the DNA in the genetic material. On the basis of the Hershey and Chase in the year 1953 Watson and Crick again performed on the same experiment and proved DNA as a genetic material and it’s defined results that are responsible for the synthesis of thousands of protein cells found in it.
