The Emergence of Bacterial Genetics. She encouraged the planting of indigenous plants such as poppies and lupins around the Stanford University campus, arguing that besides being beautiful, such plants would not need to be watered —an important consideration on a campus located in the San Francisco Bay Area , which experiences frequent droughts. Instead of returning to Columbia to finish his medical degree, Lederberg chose to accept an offer of an assistant professorship in genetics at the University of Wisconsin—Madison.

Joshua Lederberg began medical studies at Columbia's College of Physicians and Surgeons while continuing to perform experiments. Somorjai John I. Whitesides Stuart A.

All you really need to know in terms of background information is that bacteria grow into isolated colonies on plates, and that you can reproduce the colonies Telefonieren Lustig an original plate to new plates by "stamping" the original plate with a cloth and then stamping empty plates with Stuttgart Lederberg same cloth.

Bacteria from each colony are picked up on the cloth and then deposited on the new plates by the cloth. The hypothesis for the experiment is that antibiotic resistant strains of bacteria surviving an application of antibiotics had the resistance Ledefberg their exposure to the antibiotics, not as a result of the exposure.

So the penicillin-resistant bacteria were Stuttgart Lederberg in the population before they encountered penicillin.

They did not evolve resistance in response to exposure to the antibiotic. A chink Stuttgaet HIV's evolutionary armora news brief with discussion questions. Bacteria are spread out on a plate, called Dart Wetten "original plate.

They are allowed to grow into several different colonies. This layout of colonies is stamped from the original plate onto a new plate that contains the antibiotic penicillin.

Colonies X and Y on the stamped plate survive. They must carry a mutation for penicillin resistance. The Lederbergs set out to answer the question, did the colonies on the new plate evolve antibiotic resistance because they were exposed to penicillin? Search Glossary Home. Support this project.
