So, if we hybridize just these three orbitals, what we're going to end up with is our s p 2 hybrid orbitals.
我们会看到现在有3个未配对的电子,可以成键。
If I now hybridize these, if I take these and I make four symmetric, now, these are just the sp3 orbitals.
如果我将他们杂化,然后形成4个对称的轨道,这就是sp3轨道。
The best way to label this DNA is by designing probes or labels that hybridize with specific sequences that you're interested in.
最好的标记方法是,设计出能与你感兴趣的,特定基因序列杂交的,分子探针或标签
Remember, we didn't hybridize the 2 p y orbital, so that's what we have left over to form these pi bonds.
记住,我们并没有杂化2py轨道,这是我们剩下的那个行成了π键。
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
The one that does is called the sense strand and the other one is called the anti-sense strand, anti meaning it's the compliment and it will hybridize to the sense.
能够进行编码的一条链叫做正义链,另一条则叫做反义链,反义的意思是它与正义链互补,并能够与之杂交
s -- we don't have to hybridize it, it already has only one unpaired electron in a 1 s orbital.
s-我们不用杂化它,它已经有而且仅有一个未配对电子在s轨道里。
So if we go ahead and hybridize our p orbitals and our s orbitals, we'll switch from having these original orbitals to having something called hybrid orbitals.
如果我们,杂化p轨道和s轨道,我们会从原来的轨道,变成一个叫杂化轨道的东西。
We got them from combining again, 1 s orbital and the 3 p orbitals. If we hybridize these, what we end up seeing are these four hybrid orbitals.
我们把1s轨道,和3p轨道结合而得到它们,如果我们杂化它们,我们最后会看到4个杂化轨道。
We can still hybridize all these orbitals, however, so we can still form four hybrid orbitals, which are again, 2 s p 3 hybrid orbitals.
但我们仍然可以杂化这些轨道,所以我们还是可以形成4个杂化轨道,同样的,是2sp3杂化轨道。
And again, you might be thinking well, why didn't we actually hybridize this 2 p y orbital.
它来自1s和2p轨道,所以它是sp2,同样。
And if we hybridize these orbitals in carbon, what we end up with is having two hybrid orbitals, and then we're going to be left with two of our p orbitals that are each going to have an electron associated in them.
如果我们杂化碳原子里这些轨道,我们能得到两个杂化轨道,另外剩下两个p轨道,每个里面有一个电子。
So if we don't have to hybridize one of the p orbitals, we can actually end up with a lower energy situation, because now these s p 2 orbitals are 1/3 s character, and only 2/3 p character, instead of 3/4.
我们的杂化轨道就有更多的p轨道成分,所以它们的能量更高,如果我们不杂化这个p轨道,我们可以得到一个能量更低的情况。
Now if I put them in contact with one another, the plasmid that's been opened and fragments of the DNA - special fragments that I've produced with the same restriction enzyme, they'll have the same sticky ends, they will naturally hybridize with one another.
如果我让它们互相接触,已经切开的质粒和DNA片段--,这DNA片段是我已用同种限制性内切酶,处理过的特别片段,这两者会有相同的粘性末端,它们会自然地相互杂交
