Well, I think the pressing example in the United States right now has to do with people who are gay, lesbian, bisexual and transgendered.
恩,我觉得,就当前美国的情况来说,最能说明问题的例子就是,同性恋,双性恋,以及变性人。
You denature them, you can watch them denature because the egg white turns from clear to white and it doesn't go back.
它们变性了,这种变性是可以观察到的,蛋清由透明变为白色,再也变不回去
Well, I've emphasized the non-physical aspect, and I've emphasized as well that they're not changing.
我已经强调了非现实的方面,并且我也强调了他们的不变性
Now, you all know that we can make irreversible changes in proteins, you can denature them completely, that's what happens when you cook an egg for example.
现在你们都懂蛋白能够发生不可逆的改变,能够完全变性,比如在你煮鸡蛋的时候就是这样
If you repeatedly go through this cycle of denaturing, synthesizing, denaturing, synthesizing you'll get many, many copies of DNA.
如果你不断重复这个变性-复制,变性-复制的循环过程,你就会得到很多很多的DNA复制产物
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
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 operates in a similar fashion to DNA polymerase in that it denatures locally or opens up the double stranded DNA, but it's different in that it creates a new polymer from the DNA template in the language of RNA, using RNA nucleotides and not DNA nucleotides.
它的作用机制类似于DNA聚合酶,在局部使DNA双链变性,解旋,但不同的是,它合成了一个基于DNA模板的,使用RNA编码语言的新聚合物,即使用核糖核苷而非脱氧核糖核苷
