2002年人们完成了五年前开始的脊髓灰质炎病毒的基因组全序列的测定，三年后同样规模的一个团队只花了一周的时间做了一个相似长度的基因组测序。
In 2002 it took five years to develop the genomic sequence of a polio virus. Three years later it took a week for a team the same size to do the same on a virus of similar length.
方法利用聚合酶链反应（PCR）产物直接测序，对10例血液标本进行了HLA-DPB1、DRB外显子2的序列分析，并将测定结果与基因型核酸序列数据库进行比较。
Methods Sequences of HLA-DPB1, DRB exon2 of 10 samples were analysed by direct sequencing of PCR products. The results of sequencing were compared with their corresponding sequence data.
