Abstract

Moloney murine leukemia virus 35S RNA (molecular weight 3 to 3.4 × 106) is cleaved by nuclease activity present in microsomal fractions from MLV infected or uninfected mouse embryo cells to two RNA species of approximate molecular weights 1.8 × 106 and 1.5 × 106. Microsomal fractions from MLV infected and uninfected cells also contained nucleolytic activity that solubilized [3H]poly(A)·poly(U) but not [3H]poly(C) or [3H]poly(U); the cleavage of poly(A)·poly(U) was inhibited by ethidium bromide. The cleavage of MLV RNA was also inhibited by ethidium bromide, suggesting double stranded regions in 35S RNA as the site of cleavage.
