Abstract
The pattern of DNA methylation during the infection of Escherichia coli C cells with bacteriophage φX174, has been studied. In vivo methylated DNA was isolated and analyzed using the following techniques: velocity sedimentation through neutral and alkaline sucrose gradients, isopycnic analysis, chromatography on benzoylated DBAE-cellulose columns and specific enzymatic digestion. All these analytical methods indicated that the DNA molecules that are methylated during the process of phage φX DNA replication are the replicating intermediates composed of a circular complementary strand and a viral strand larger than one genome length. It is concluded that methylation occurs on the nascent DNA strand of the replicating intermediates involved in the synthesis of progeny single-stranded DNA.
