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

which of the following is the correct prediction of moi measurement?

In E. coli, the five contiguoustrp genes encode enzymes that sythesize the amino acid tryptophan. These genes are expressed efficiently only when tryptophan is limiting. The genes are controlled by a repressor, just as the lac genes are, although in this case, it is the absence of its ligand (tryptophan) that relieves repression, match trp genes to their gene product,
