Study notes for the main scientists that participated in the early discovery of DNA and the early studies about DNA

-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. …

…into their DNA <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
