-Hershey and Chase showed that DNA is the hereditary material of phages
-Hershey and Chase labeled protein in a T2 phage with a radioactive tag
<Tab/>-Then they labeled DNA in a separate batch of phage with a radioactive isotope
<Tab/>-Both batches of tagged phages were allowed to infect separate batches of E.Coli bacteria
<Tab/>-Afterwards, both sets of E. Coli. …showed first 75 words of 580 total…

<Tab/>-Then they transferred the bacteria to a medium containing a lighter more common isotope of nitrogen
<Tab/><Tab/>-Any new DNA that the bacteria synthesized would be lighter than the other DNA made in the 15N medium
<Tab/>-Results of centrifuging the bacterial DNA eliminated other two models for DNA replication and proved Semiconservative model
