5.3 DNA is the genetic material

. DNA is the genetic material Many biologists despite the earlier experiments of Griffith, Avery and others, still believed that protein, not DNA, was the hereditary material in a cell. As eukaryotic chromosomes consist of roughly equal amounts of protein and DNA, it was said that only a protein had sufficient chemical diversity and complexity to encode the information required for genetic material. In , however, the results of the Hershey-Chase experiment finally provided convincing evidence that DNA is the genetic material.
