Mutation resulting from lack of a mismatch-repairsystem

Reference no: EM13529658

MC4100 mutS cells are spread onto a single LA/λvir plateand incubated overnight at 37° C. The next day there aremultiple bacterial colonies growing on the plate. Decide whethereach of the following (A-C) could account for the bacterialresistance to λvir:

I. This could account for the bacterial resistance toλvir.

II. This could NOT account for the bacterial resistance toλvir.

C. A mutation in malK

B. A spontaneous mutation resulting from lack of a mismatch-repairsystem

A. A mutation preventing λvir from entering the bacterial cell
