Hershey and Chase showed that the introduction of deoxyribonuclease (referred to as DNase ), an enzyme that breaks down DNA, into a solution containing the labeled bacteriophages did not introduce any 32 P into the solution. This demonstrated that the phage is resistant to the enzyme while … Zobacz więcej The Hershey–Chase experiments were a series of experiments conducted in 1952 by Alfred Hershey and Martha Chase that helped to confirm that DNA is genetic material. While DNA … Zobacz więcej Hershey and Chase needed to be able to examine different parts of the phages they were studying separately, so they needed to distinguish the phage subsections. Viruses were known to be composed of a protein shell and DNA, so they chose to uniquely label … Zobacz więcej The Hershey–Chase experiment, its predecessors, such as the Avery–MacLeod–McCarty experiment, and successors served to unequivocally establish that hereditary information was carried by DNA. This finding has numerous … Zobacz więcej In the early twentieth century, biologists thought that proteins carried genetic information. This was based on the belief that proteins were more complex than DNA.
