Vedclass · Answer

(D) The replica plating experiment,famously conducted by Joshua and Esther Lederberg,was used to demonstrate the genetic basis of antibiotic resistance in bacteria.In this experiment,a master plate containing bacterial colonies was pressed onto a velvet-covered block and then transferred to new plates containing a medium supplemented with the antibiotic streptomycin.The streptomycin acts as a screening agent (or selective agent) to identify colonies that possess the genetic mutation for antibiotic resistance.Only those colonies that have the resistance gene can grow on the streptomycin-supplemented medium,while others are inhibited.
