History of DNA Replication-I
1865 Medelian Inheritance 1869 DNA Isolated 1952 Viral Replication Lederberg and Zinder described transduction, which is the transfer of genetic information by viruses. ulbecco showed that single particles of an animal virus can produce areas of cellular lysis called plaques. With Baltimore and Temin, Dulbecco was awarded the Nobel Prize in Medicine and Physiology in 1975. Hershey and Chase published data suggesting that only DNA is required for T2 bacteriophage replication. Luria and Human, and independently Weigle, described a non-genetic host-controlled modification system in bacteriophage which ultimately led to the study of bacterial systems of restriction and modification; these studies in turn eventually led to the discovery of restriction endonucleases, essential tools in the development of genetic engineering methodologies. 1953 DNA Helix JD Watson & Crick????
