In his analysis of rII in phage, Benzer assayed complementation
Suppose you try your hand at this with several mutants and get the following results (+ = complementation): 42 and 62 + 42 and 83 – 62 and 63 – 62 and 74 + 42 and 74 – 42 and 75 + 62 and 75 – Mutation 42 has previously been shown to be in a different gene than mutation 62. What can you conclude? A) Mutations 42 and 75 are in the same gene.
B) Mutations 62 and 74 are in the same gene.
C) Mutations 62, 63, and 74 are in the same gene.
D) Mutations 42 and 74 are in the same gene.
E) Mutation 63 is not in the same gene as either 62 or 42.
