Hershey-Chase Experiment: In 1952, Alfred D. Hershey and Martha Chase performed a confirmatory experiment using T2 bacteriophage to prove DNA as genetic material. Bacteriophage T2 is a tailed virus of Escherichia coli. Viruses are the simplest living organisms and their reproduction is totally dependent on the metabolic machinery of the host. The viruses infect the bacteria and are called as bacteriophage. Bacteriophage T2 which infects the bacteria is composed of about 50% protein coat and 50% with an inner core of DNA. The bacteriophage T2 attaches the host bacterium by means of a tail. It enters its DNA into the … Continue reading Hershey-Chase Experiment Prove that DNA is the Genetic Material
