✦ Synopsis

High levels of pyrimidine deoxyribonucleosides, but not purine deoxyribonucleosides, increase the reversion rate of bacteriophage T4rH mutants to r +. This increased reversion rate is not observed when a thymidine kinase mutation is introduced into the bacteriophage, but the high reversion rate persists when the host, E. coli, harbors a thymidine kinase mutation.
