Abstract

Kinetic analysis of the reassociation of DNA synthesized in vitro by a murine leukemia virus DNA polymerase revealed two classes of double-stranded product representative of 25 and 100 percent of viral genetic information. The DNA product representing the smaller portion of the viral genome comprised 85 percent of the double-stranded DNA generated in vitro and was extensively duplicated in the genomes of both normal cells and cells containing RNA tumor virus.
