Evidence that mismatched bases in heteroduplex T4 bacteriophage are recognized in vivo.

RESUMO
T4 heteroduplex heterozygotes are lost selectively after prolonged incubation of phage-infected Escherichia coli cells under nonreplicating conditions. The loss of heterozygosity occurs for four out of six rII sites tested and is not dependent upon T4 v gene function. The results are interpreted to indicate the existence of a base-specific system for the recognition of mismatched bases in intracellular DNA.
