Verified step by step guidance1
Understand the context of each experiment mentioned in the problem to determine their contributions to the discovery of DNA as the genetic material.
Oswald Avery's experiments demonstrated that DNA is the substance that causes bacterial transformation, which was a key step in identifying DNA as the genetic material.
Watson and Crick's discovery of the DNA double helix provided the structural basis for understanding how DNA can store and transmit genetic information.
The Hershey/Chase experiments used bacteriophages to show that DNA, not protein, is the genetic material, further confirming the role of DNA.
Barbara McClintock's experiments with maize focused on genetic elements known as transposons, which were important for understanding genetic regulation but not directly related to identifying DNA as the genetic material.
