The correct complement is made because of these principles of Watson-Crick base pairing that we talked about before.
剪接配对的正确性源自,沃森克里克碱基互补配对原则的作用,这我们讲过的
-
It's oriented in the oppose direction and it has the complementary base pairs at each position.
它们方向相反,并且所有的碱基都是互补的
-
I just give you one of those, right, because you could write down the other one because you know the other complimentary sequence from base pairing?
我只写了一条链的序列,因为你们能够写出另一条,因为你们根据碱基配对,就能推测出互补链的序列
-
Translation occurs by a special kind of polymerization where these transfer RNA's operate by Watson-Crick base pairing.
翻译过程是一种特殊的聚合过程,当tRNA按照,沃森克里克碱基互补配对原则进行配对
-
The DNA molecule here has been spread apart, opening up two single stranded DNA's which have complementary base sequences because they were double stranded DNA.
这里DNA分子被分开,形成两条单链DNA,这两条单链碱基序列互补,因为它们是由双链DNA解旋形成的
-
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
-
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
-
If I'm talking about two DNA strands and they differ only in one or two base pairs they won't be exact complements and they won't form this double helix.
假设有两条DNA单链,有一两个碱基不能配对,它们就不能完全互补,也无法形成双螺旋形结构
-
Well you do that by this Watson-Crick base pairing, so I know if I have I know what messenger RNA to make from that because I have to satisfy these base pairing rules.
依据的是沃森克里克碱基互补配对原则,如果给我一个ACGCGA的序列,就能知道转录出的mRNA会是什么,因为我必须满足碱基配对原则
