parental replicative-form ( rf ( * ) ) dna of bacteriophage varphix174 in a replication-deficient host cell ( rep ( 3 ) ( - ) ) exhibits two characteristic features that correlate the function of viral gene a with the initiation of viral dna replication : a specific discontinuity in the viral strand of a constant number of rf molecules and elongation of the viral strand to yield replicative-intermediate dna forms with single-stranded tails .
