The antibiotic used in Lederberg's replica plating experiment was :
Open in App
Solution
The correct option is A Penicillin
With their replica plating experiment, Lederberg's showed that antibiotic-resistant strains of bacteria surviving an application of antibiotics had the resistance before their exposure to the antibiotics, not as a result of the exposure. They used Penicillin for their experiment.Their experiment showed how adaptations are already present at the genetic level and not produced due to the conditions in which the organism needs to adapt. So, the correct option is 'Penicillin'.
