h-1 dna was isolated from human or hamster cells infected with a temperature-sensitive mutant , ts1 , which is deficient in progeny single-stranded dna synthesis at the restrictive temperature ( s.l . rhode , 1976 ) , thus minimizing possible confusion between rf and progeny dna replicative intermediates ( ris ) .
