VSV defective interfering particles of various sizes and from several independent sources frequently contain plus and minus strand RNA. In many cases some of the complementary strands are covalently linked as snap-back molecules. Infectious particles on the other hand package little or no plus strands. Snap-back molecules from the three different sources examined so far vary in size but appear to conform to the same overall linear duplex structure with cross-links at the ends only. They each contain a base sequence which is a subset of the next larger one and appear to correspond to unique sequences in the L cistron of the genome. Possible origins for these snap-back molecules are discussed.
来自多个独立来源的各种大小的水泡性口炎病毒（VSV）缺陷干扰颗粒通常含有正链和负链RNA。在许多情况下，一些互补链作为回折分子共价连接。另一方面，感染性颗粒包装很少或没有正链。到目前为止所检测的来自三种不同来源的回折分子大小不同，但似乎符合相同的整体线性双链结构，仅在末端有交联。它们各自包含一个碱基序列，该序列是下一个更大序列的一个子集，并且似乎对应于基因组L顺反子中的独特序列。文中讨论了这些回折分子可能的起源。
