But they will do that in a very particular way, in that only strands that exactly match will be able to reform their native structure.

但是双链的形成也不是随意的,只有完全互补的单链之间,才成重新恢复到它们原先的结构

If I took two double stranded DNA molecules and I exposed them to certain conditions that caused them to denature, that means its native structure falls apart.

假如我把两条DNA双链,放在特定的条件下,使它们变性,变性表示使它们的原始结构分开

The native structure is this double stranded structure here and if I heat it up slightly and I add some base, so under slightly basic conditions, these molecules will fall apart because you've created conditions where the hydrogen bonding is no longer favorable so they peel apart.

原始结构,在这里就是指DNA双链,如果我稍微加热,并且加入一些碱,在弱碱性的条件下,这些配对碱基会分开,这是因为在一定条件下,碱基对之间的氢键,不再稳定并且会断裂分开
