Characterization of the U stretch region in the 3′ NCR of the vRNA

Segment	U residues	Distance from 5′ end of vRNA
1	4	14
2	4	14
3	4	13
4	5	13
5	3	15
6	4 - 5	14
7	4	14
8	4	13

For each segment, the number of residues comprising the U stretch and the distance from the terminal nucleotide of the 5′ NCR are reported.
