Question 6

Seymour Benzer found which of the following while studying 20,000 mutants of the rII region of the T4 bacteriophage?

Accepted Answer

A)  Intragenic recombination between mutants with partial deletions and point mutations could be used to map the position of individual rII mutations. 
B)  Deletion- mapping analysis found that a point mutation and a deletion mutation whose locations overlapped resulted in wild- type intragenic recombinants. 
C)  The size of the plaques on E. coli lawns determined the distance between rIIA and rIIB. 
D)  Intragenic recombination analysis could determine the distance between rIIA and rIIB. 
E)  Simultaneous infection of rII phage mutants resulted in T4 plaques when the mutations were in the same rII gene.
