Hershey and Chase concluded that DNA, not protein, was the genetic material. They determined that a protective protein coat was formed around the bacteriophage, but that the internal DNA is what conferred its ability to produce progeny inside a bacterium. They showed that, in growth, protein has no function, while DNA has some function.
Experiments conducted in 1952 by Alfred Hershey and Martha Chase demonstrated how the DNA of viruses is injected into the bacterial cells, while most of the viral proteins remain outside. [1] [2] The injected DNA molecules cause the bacterial cells to produce more viral DNA and proteins. These discoveries supported that DNA, rather than ...
The Chase Dietary Method is an alternative cancer treatment proposed by osteopathic physician Alice Chase (1898–1974). Medical experts have described the Chase Dietary Method as ineffective and potentially hazardous to health. [1] [2] [3] The Chase method is based on the discredited idea that retained waste in the body causes tumours.
In 1952, Hershey and Chase [19] provided key evidence that the phage DNA, as distinct from protein, enters the host bacterial cell upon infection and is thus the genetic material of the phage. This finding suggested that DNA is, in general, the genetic material of different organisms.

In 1971, he edited The Bacteriophage λ, an extensive volume on the subject, published by CSHL Press that same year. [1] In 1981, Hershey became a founding member of the World Cultural Council. [9] Hershey died from congestive heart failure on May 22, 1997 at his home in Laurel Hollow, New York. [10] He was 88 years old.
