Benzer's Analysis of Phage Genomes Included Deletion Mapping

Multiple Choice

Benzer's analysis of phage genomes included deletion mapping. Since recombination could not occur in the area of a deletion, an infection by two phage strains, one of which has a deletion and the other a point mutation, that results in no wild- type recombinants being produced indicates_________ .

A) that the deletion includes the position of the point mutation in a different gene
B) the distance between the two types of mutation
C) that the point mutation is recessive
D) that the deletion includes the position of the point mutation in the same gene
