Answer:
As DNA contain phosphorus in its structure in large amount, therefore, Harshey and Chase labeled DNA with radioactive phosphorus and because protein contains some amino acids which have sulfur so they labeled T2 bacteriophage protein with sulfur.
So after that they infected E.coli bacteria with radioactively labeled phages and after centrifugation, they have found that pellet which contains cells is showing the presence of radioactive phosphorus and supernatant which have T2 phage capsid protein showing the presence of radioactive sulfur.
Therefore by labeling viral protein and viral DNA they found that DNA is the genetic material not protein.

The appropriate response is Monosodium Glutamate. Unadulterated MSG is accounted for to not have a wonderful taste to the point that it is joined with an exquisite fragrance. The fundamental tactile capacity of MSG is credited to its capacity to upgrade flavorful taste-dynamic mixes when included the best possible concentration. The ideal fixation differs by nourishment; in clear soup, the joy score quickly falls with the expansion of more than one gram of MSG for each 100 mL.
