Amber Mutant of Bacteriophage Qβ Capable of Causing Overproduction of Qβ Replicase


Amber mutant amB86 of bacteriophage Qβ is capable of causing the production of five to eight times more viral replicase than wild-type phage. Su bacteria infected with the mutant can carry the viral RNA in a plasmid-like state for many bacterial generations.
