Mutants 1 and 2 are two point mutations of riia. mutant 1 does not overlap with mutant 2. mutants 3 and 4 are two deletion mutations of riib. mutant 3 overlaps with mutant 4. mutant 5 is a deletion that overlaps mutants 2 and 4, but does not overlap mutants 1 and 3.

for each of the following crosses, you perform a high m. o.i infection of both mutants on e. coli strain b. then you harvest the lysate and perform a high m. o.i infection on e. coli strain k. finally, you dilute this second lysate and perform low m. o.i infections on separate plates with e. coli b and e. coli k.

predict the results by circling one answer per cross. select "equal number" if the e. coli b and e. coli k plates will have some plaques in equal proportions; select "no plaques" if both plates will show 0 plaques; select "can’t tell" if the information provided is insufficient to predict the result with certainty.

indicate if it it: more on e coli b, equal number, no plaques, or can't tell for each of the options below.
