title: [Sedimentation properties of virion RNA of Newcastle disease virus after annealing under different conditions].
abstract: After annealing at high temperatures 50S RNA of Newcastle disease virus was partially degraded. The resulting fragments had the sedimentation coefficient of 23--32S. Solution of dimethylsulfoxide and formamide were used to decrease the temperature of annealing. However, annealing with denaturating agents caused agglomeration of 50S RNA molecules. This phenomenon is discussed.
