RESUMO

Mason-Pfizer monkey virus 60-70S RNA has a molecular weight of 8 times 10-6 when analyzed on polyacrylamide gels. Dissociation of 60-70S RNA of Mason-Pfizer monkey virus and murine leukemia virus by heat or formamide (40%) resulted in conversion to identical subunit structures of 2.8 times 10-6 daltons; treatment with lower amounts of formamide revealed a partial dissociation of Mason-Pfizer monkey virus 60-70S RNA released three low-molecular-weight RNA species of 10-5, 3,5 times 10-4, and 2.5 times 10-4.
