Effect of DNA-negative and maturation-defective conditions on accumulation of functional messengers for T4 bacteriophage-specific dihydrofolate reductase and deoxynucleoside monophosphate kinase

Abstract

Messengers for T4 phage-specific deoxynucleoside monophosphate kinase overaccumulated in nonpermissive hosts infected with amber-defective viruses that displayed either the DNA-negative or maturation-defective phenotype. Under both conditions, however, transcription of functional messengers for dihydrofolate reductase followed essentially normal kinetics.
