Which of the following statements is false regarding the experimental system Benzer used to perform fine mapping of the rII locus: A. In co-infection experiments, two mutations that do produce lysis in trans, but do not when in present in cis are in the same complementation group B. The rII- mutants, when plated on E. coli K (lambda) cells do not produce plaques. C. In co-infection experiments, two mutations that do not produce lysis in trans but do so when in cis are in the same complementation group D. The rII- mutants, when plated on E. coli B cells produce plaques that are larger and more distinct (with sharp edges) than plaques formed by rII+ wild type phages. E. Benzer's point mutants could revert or recombine while deletions could not
