Describe the results of three experiments that to show dna is the genetic material

The three experiments are:

Griffith performed an experiment by which he observed that harmless R strain of the bacteria transformed into harmful S strain when mixed with heat-killed S strain.

He concluded that the "transforming principle" from the heat-killed S strain bacteria transformed the R strain.

They identified that the nature of the transforming principle mentioned by Griffith.

They used digestive enzymes such as proteases, RNase, and DNase.

They conclude that the transforming principle was DNA in nature.

They used radioactive sulfur to label proteins and radioactive phosphorus to label DNA in the bacteriophage.

The infected bacteria were blended and centrifuged.  

The radioactive phosphorus, that is, DNA was found inside the cell whereas the radioactive sulfur, that is, proteins were found outside the cell.

It also proved that the genetic material was DNA, not protein or RNA.

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.
