Visna virus 70S RNA contains long stretches of polyadenylic acid [poly(A)]. The homogeneity in length of poly(4) regions is observed in 70S RNA from visna virus and all RNA tumor viruses tested, and not with other types of RNA. By this criterion visna virus resembles RNA tumor viruses.
维斯纳病毒70S RNA含有长链的聚腺苷酸[poly(A)]。在维斯纳病毒的70S RNA以及所有测试的RNA肿瘤病毒中,均观察到聚(A)区域长度的均一性,而在其他类型的RNA中则未观察到。根据这一标准,维斯纳病毒类似于RNA肿瘤病毒。
