Multiple Choice
The episome in an Hfr strain is inserted near the trp (tryptophan operon) locus.This Hfr strain is grown with an F- Trp- strain.From this mating, we isolate an F+ Trp+ strain that can readily impart the Trp+ phenotype to F- Trp- strains, but no other traits are ever transferred.(When the original Hfr strain is mated with F− strains, traits other than Trp+ can be transferred, although at lower frequency than Trp+. ) What most likely has happened?
A) An F′ trp+ plasmid has been generated.
B) Mutation occurred.
C) Transduction occurred.
D) Transformation occurred.
