Divergence of nucleotide sequences of different regions of the genome of isolate P2S/Mog66-4 from those of isolate P1W/Bar65 and of the three Sabin strainsa
| Virus | Divergence (%) of genomic region (length in nucleotides):

|||||||||
|---|---|---|---|---|---|---|---|---|---|---|
| 2A (400) | 2B (291) | 2C (987) | 3A (261) | 3B (66) | 3C (549) | 3D (1,383) | 3′UTR (71 and 72) | P2 (1,678) | P3 (2,259) | |
| Bar65 | 24.5 | 21.6 | 19.6 | 9.6 | 0 | 6 | 10.6 | 2.8 | 21.1 | 9.0 |

The lengths of appropriate regions are indicated in parentheses in the column headings. Only 400 3′-terminal (non-Sabin) nucleotides of the 2A coding region were used for the calculations of values representing 2A and P2. The lengths of the 3′-untranslated regions (3′UTR) in Sab1 and Sab2 RNA are 72 and 71 nucleotides, respectively.
