Transformation. Electroporation. Antibiotic selection. Genetic transformation of bacteria had been discovered in the 1920’s, but gene cloning became possible only after restriction enzymes and plasmids became available in the 1970’s. Where do restriction enzymes …

Transformation A change in phenotype when bacterial; cells take up foreign genetic material. Oswald Avery In 1944 at the Rockefeller Institute, he showed that the activity of the then-unknown material responsible for transformation was not affected by protein-destroying enzymes. But the activity was stopped by DNA-destroying enzymes.

_____ Griffith discovered transformation in bacteria. _____ Mice injected with non-encapsulated bacteria quickly became sick and died. _____ Encapsulated bacteria can become "naked" bacteria. _____ Bacteria that are naked tend to be harmless. _____ Naked bacteria can develop a capsule only after exposure to the DNA of encapsulated bacteria.

History of Bacterial Transformation and Plasmids | Bacterial Transfo…
Gene exchange between bacteria. A. Transformation. The uptake of naked DNA molecules and their stable maintenance in bacteria is called transformation. The phenomenon was discovered in 1928 by Griffith, who was studying the highly virulent pathogen Streptococcus pneumoniae.
