They prepared two samples of phage: ³⁵S, which labels protein and ³²P, which labels DNA. It was found that only ³²P entered the bacterial cells, indicating that DNA, not protein, is the genetic material. Key Terms
WitrynaGriffith's experiment, [1] reported in 1928 by Frederick Griffith, [2] was the first experiment suggesting that bacteria are capable of transferring genetic information through a process known as transformation. [3] [4] Griffith's findings were followed by research in the late 1930s and early 40s that isolated DNA as the material that ...
WitrynaIn 1952, Alfred Hershey and Martha Chase published a convincing demonstration that DNA (not protein) was the genetic material. The Hershey–Chase experiment was carried out with a virus, called bacteriophage T2, that infects bacteria. Bacteriophage T2 consists of little more than a DNA core packed inside a protein coat. rawcreations.beWitryna7 lis 2024 · Hershey and Chase conducted a series of three experiments in which protein and DNA of bacteriophages were labeled with radioactive isotopes.
