Question

Replica plating is a technique that allows the same bacterial colonies to be plated onto different media. A sterile velvet pad is pressed onto a “master” plate to pick up bacteria from each colony. The pad is then pressed onto new plates to reproduce the same colonies on other media. For help understanding which genotypes grow on each medium type, use the Hint. Use these data to deduce the number of exconjugants with each genotype.

Step 1

- Replica plating lets us identify the same bacterial colonies across different media - Each medium can select for or against specific genotypes - By comparing growth patterns across plates, we can determine genotypes Show more…
