Structure of the Ribonucleoprotein of Influenza Virus

摘要: Abstract The ribonucleoprotein (RNP) internal components of influenza virus were separated into distinct size classes by sedimentation in glycerol gradients and examined electron microscopy using positive staining with uranyl acetate. The large RNP have a peak length distribution at 90 to 110 nm, the medium, 60 small, 30 50 nm. These lengths can be correlated estimated molecular weights ribonucleic acids contained various classes. structure appears consist strand which is folded back on itself coiled regular double-helical arrangement.
