Abstract

Electron microscopy, isopycnic centrifugation, thermal denaturation profiles and polyacrylamide gel electrophoresis were used to characterize the nucleic acid from neonatal calf diarrhea virus. The genome was shown to consist of 11 segments of double-stranded RNA. The molecular weights of the segments were determined to be: (in million dalton units) 2.18 ± .06, 1.73 ± .07, 1.64 ± .06, 1.48 ± .06, 0.94 ± .03, 0.77 ± .02, 0.50 ± .03, 0.50 ± .03, 0.50 ± .03, 0.29 ± .03, 0.22 ± .02. Six NCDV capsid polypeptides are described. The molecular weights of the capsid polypeptides ranged from 0.15 x 105-1.27 x 105 daltons. A possible direct coding relationship for the capsid polypeptides was indicated.
