DNA molecules of B. subtilis phage SPP1 exhibit terminal redundancy and are partially circularly permuted. This was established by the hybridization of selected EcoRI restriction fragments to single strands of SPP1 DNA and by an analysis of the distribution of denaturation loops in partially denatured SPP1 DNA molecules. Deletions in SSP1 DNA are not compensated by an increase in terminally repetitious DNA. This finding, which is unique to SPP1, is discussed in terms of a modification of the Streisinger/Botstein model of phage maturation.
枯草芽孢杆菌噬菌体SPP1的DNA分子表现出末端冗余且部分呈环状排列。这是通过将选定的EcoRI限制性片段与SPP1 DNA单链杂交以及分析部分变性的SPP1 DNA分子中变性环的分布来确定的。SPP1 DNA中的缺失不会通过末端重复DNA的增加来补偿。这一SPP1特有的发现，根据噬菌体成熟的斯特赖辛格/博特斯坦模型的修正进行了讨论。
