Question

Replica plating involves transferring bacterial colonies from one agar plate to another, allowing for the identification of specific mutants based on changes in their growth or appearance. In this case, replica plating can be used to identify colonies that do not produce pigment, indicating a mutant strain of Serratia marcescens. Positive phenotypic selection, DNA sequencing, and environmental searching are not likely to be successful in identifying a specific mutant strain that does not produce pigment.
