[The presence of non-integrated SV40 viral DNA in nonproductive cells transformed by this virus].
The hot phenol extraction of nuclic acids reveals the presence of small amounts of nonintegrated SV 40 DNA in transformed syrian hamster or mouse cells. The extractibility of the viral DNA is influenced by its conformation; SV 40 DNA, form I is preferentially extracted by contrast with form III DNA.
