In a plaque assay experiment, a phage stock solution containing 5.7 * 102 pfu/mL was diluted and plated on nutrient agar plates with bacterial hosts. For the 10-5 dilution plate, the expected number of plaques is approximately 0.57. For the 10-4 dilution plate, the expected number of plaques is approximately 5.7.

1. In a plaque assay, 100uL of phage stock solution containing 5.7 * 102 pfu/Ml is mixed with 0.9 mL
of solution containing host bacteria. Further decimal serial dilutions of this mixture are made. 1 mL
of each dilution is added to a nutrient agar plate. What is the average number of plaques you
anticipate to count for phage samples that were incubated on the following dilution plates. 1) 10-5
dilution plate 2) 10-4 dilution plate
