Answer:

The three experiments are:

  • Griffith experiment

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.

  • Avery, McCarty, and MacLeod- Identification of transforming principle

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.

  • The Hershey-Chase experiment

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.
