It exists in a double stranded form where every strand is matched by its complement.

这种碱基配对存在于DNA双链中,每条单链都与其互补链,通过这个原则配对组合

Hybridization simply means that DNA will re-nature and form a stable double helix only with its particular match, only with the hybrid that it is perfectly complementary, too.

核酸分子杂交表示,DNA在变性状态下可以恢复活性,和与其配对的单链形成稳定的双螺旋结构,只有在完全配对时才会发生这种情况

It has to do with the nature of this complementary binding between double stranded DNA and the fidelity of this base pair matching in forming stable DNA molecules.

这些特性能从根本上解释,为何DNA双链的碱基能互补配对,以及在形成稳定的DNA分子结构时,碱基互补配对为何具有一致性
