Two mutants of poliovirus have been isolated, one (MutX) with a mutation in gene X and the second (MutY) with a mutation in gene Y. If cells are infected with each mutant alone, no virus is produced. If a cell is coinfected with both MutX and MutY, which one of the following is most likely to occur? (A) Reassortment of genome segments may occur and give rise to a viable wild-type virus.
(B) The genomes may be reverse transcribed to DNA and both MutX and MutY viruses produced.
(C) Complementation between the mutant gene products may occur and both MutX and MutY viruses produced.
(D) The cells will transform at high frequency because they will not be killed by the poliovirus mutants.
