Evidence of 5'-terminal modification in the kemerovo virus double-stranded RNA segments and its removal by treatment with alkaline phosphatase.

Only one strand of each double-stranded (ds) RNA segment of the Kemerovo virus genome was 5'end-labelled using gamma-32P-ATP and T 4 polynucleotide kinase after preceding dephosphorylation of 5'ends by calf intestinal alkaline phosphatase. This suggests a 5'-terminal modification of the one of complementary strands in the ds RNA segments.
