Viral Transduction Bacterial DNA is transferred from one bacterium to another by a virus. http://en.wikipedia.org/wiki/Transduction_(ge netics)
Bacterial ConjugationOne bacteria transfers beneficial DNA to another. Example: gene that codes for antibioticresistance. http://en.wikipedia.org/wiki/Bacterial_conjugation
History of Recombinant DNA1972 - The idea for recombinant DNA was first proposed by PeterLobban, a graduate student at Stanford University Medical School.1972 -73 - The first publications describing the successful production andintracellular replication of recombinant DNA appeared.1974 – Patent on recombinant DNA was awarded in 1980.1982 - The first licensed drug generated using recombinant DNAtechnology was human insulin, developed by Genentech and Licensed byEli Lilly and Company. http://en.wikipedia.org/wiki/Recombinant_DN A#History_of_recombinant_DNA

Applications: The GloFish is a patented and trademarked brand of genetically modified (GM) fluorescent zebrafish with bright red, green, orange- yellow, blue, and purple fluorescent colors. One of the first genetically modified animals to become publicly available as a pet. http://en.wikipedia.org/wiki/GloFish

1. Plasmid DNA andhuman DNA are 2. Sticky ends ontreated with the same the human DNArestriction enzyme. containing the insulin gene are complementary to sticky ends on the plasmid. 3. Ligase is used to join sticky ends. 4. Bacteria containing plasmid with human insulin gene makes insulin.
