Part b who demonstrated that dna is the genetic material of the t2 phage? who demonstrated that dna is the genetic material of the t2 phage? franklin meselson and stahl darwin and wallace watson and crick hershey and chase

The correct option is D. Hershey and Chase

Explanation:

Experiments carried on by Hershey and Chase proved that DNA is the genetic material. It discarded the former belief that proteins were the genetic material.

Hershey and Chase carried out their experiments by using radioisotope of phosphorus (32P) and sulphur (35S) to prove their point. Phosphorus is present only in DNA whereas sulphur is present in proteins but absent in DNA. Hence, the usage of these isotopes acted as radioactive markers to prove the results of their experiments.

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
