Those are two continuous strands that wind around each other to form the double helix.
这两股主链,相互缠绕形成双螺旋
-
They would naturally hybridize and form a duplex, or a double stranded nucleic acid.
它们会自然杂交并形成双螺旋,或者说双链核酸
-
This is - what this diagram shows you is-- the forces that hold these individual strands of DNA into a double stranded form.
你们可以看看这个图表,演示了连接两条DNA长链为双螺旋,结构的化学力
-
I'm going to start by talking about a very specific and interesting form of double stranded DNA called a plasmid and plasmids occur in nature.
我要从一种十分特殊,并有趣的双链DNA开始,这种双链DNA被称为质粒,它在自然界就存在
-
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
-
The result of this process if this replication went down the whole length of the DNA would be to form two identical, double stranded DNA molecules.
如果复制过程在整条链上持续进行的话,将生成两条完全一样的,双链DNA分子
-
That only strands that have this exact complement can form double stranded DNA.
这表示只有两条链的碱基对,完全互补才能形成DNA双链
-
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
-
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
