Question

A phage-Infected bacterial culture was subjected to a series of dilutions, and a plaque assay was performed in each case, with the results shown in the following table. Which of the following explains the result of the 10^4 and 10^5 dilutions? Select all correct statements. In the 10^4 dilution, the concentration of phage is too high. In the 10^4 dilution, the concentration of phage is too low. In the 10^6 dilution, the concentration of phage is too high. In the 10^6 dilution, the concentration of phage is too low.

Explanation / Answer

Answer: Options A and D are correct.
Explanation:
In 10^4 dilution, the phage concentration is too high. Hence all the bacterial cells are lysed.
In 10^6 dilution, the phage concentration is too low. Hence no bacterial cell is lysed.
