Adjacent Z-DNA contributes to the formation of homologous DNA triplex
Whether the homologous parallel triplex (HP-triplex, formed by dsDNA and a homologous ssDNA) acts as an intermediate prior to DNA recombination remains controversy, owing to the intrinsic instability and lake of experimental data. Here, we report a HP-triplex that is stable at least at 35 oC under protein-free conditions. Two complementary circular ssDNAs were first hybridized at a 1:1 ratio to…
