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.

explanation:

mark brainliest!

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
