A more stable derivative of IS2-6 has been isolated, which had lost 54 bp of the 108 bp long insert characteristic of IS2-6. This new allele of IS2, IS2-61, segregates the remaining 54 bp to yield allele IS2-611. DNA sequence analysis shows that the segregation products of IS2-6 arise by recA-independent, illegitimate recombination at 9 bp long direct sequence repetitions.
已分离出一种更稳定的IS2 - 6衍生物,它失去了IS2 - 6特有的108 bp长插入片段中的54 bp。IS2的这个新等位基因IS2 - 61,将剩余的54 bp分离出来产生等位基因IS2 - 611。DNA序列分析表明,IS2 - 6的分离产物是通过recA非依赖的、在9 bp长的直接序列重复处发生的非法重组产生的。
