Physiological Evidence

Q. Using imprints from a plate with complete medium and carrying bacterial colonies, you can select streptomycin resistant mutants and prove that such mutations do not originate as an adaptation. These imprints need to be used

1. On plates with and without streptomycin
2. Only on plates with streptomycin
3. On plates with minimal medium
4. Only on plates without streptomycin
