title: Polar mutations in the left arm of bacteriophage lambda i434.
abstract: By studying complementation between frameshift and nonsense mutants located in the structural genes for the head of bacteriophage lambdai434, we found mutations in gene B which are polar on genes C and D and one mutation in gene E which is polar on gene F.
