An important trait that some bacteria have is resistance to tetracycline (a broad-spectrum antibiotic). Other bacterial strains are inhibited by tetracycline (they cannot reproduce and form colonies in its presence). Your challenge: diagram and briefly describe an experiment to test the hypothesis that the tetracycline resistance is a trait that is inherited and encoded by DNA. Hints: look to the experiments of Griffith and Avery, MacLeod, and McCarty for guidance; ideas for materials: Tetracycline-resistant bacteria culture (Tcr cells), tetracycline-sensitive bacteria culture (Tcs cells), agar plates with tetracycline, test tubes, boiling water.
