Multiplicity of infection (moi) is a measure of how many phage particles infect a given bacterial cell within a population?
a) If the average number is one or fewer phage particles per cell, the infection is more likely to result in lysis
b) If the number of phage particles is two or more, it is more likely to produce lysis
c) If the average number is one or fewer phage particles per cell, the infection is more likely to result in lysogney
d) If the number of phage particles is two or more, it is more likely to produce lysogney
