title: Characterization of bluetongue virus ribonucleic acid.
abstract: An improved purification procedure yielded bluetongue virus free from any single-stranded ribonucleic acid (RNA) component. Double-stranded RNA obtained from purified virus or isolated from infected cells was fractionated into 5 components by means of sucrose gradient sedimentation analysis, and into 10 components by electrophoresis on polyacrylamide gels. The size of these components vary from 0.5 x 10(6) to 2.8 x 10(6) daltons, with a total molecular weight estimate of about 1.5 x 10(7) for the viral nucleic acid. The denaturation of the genome and separation of the resulting fragments are also discussed.
