They will smear to give you something like this where here are the two nuclei.
他们会形成这样的结构,这是两个核。
-
Lipids are really complex molecules on their own right, but because of their particular kind of complexity they allow certain biological structures to form.
脂类本身是非常复杂的分子,但正是它们独特的复杂性,使它们能够形成某些生物结构
-
The two lobes smear and I end up with something that looks like this.
最终，叶与叶重叠,形成这样的结构。
-
In order to have a completely balanced diet that's completely plant based, one has to be very careful about having a wide array of foods.
为了形成一个完全以素食为主的,平衡饮食结构,你必须非常注意,广泛摄入各类食物

So, what I want to do is start off small, with the smallest interesting part of the brain and then get bigger and bigger and bigger talk about how the small part of the brain, the neurons, the basic building blocks of thought, combine to other mental structures and into different subparts of the brain and finally to the whole thing.
我将从细微入手,从大脑最细微的部分开始,然后逐步扩大,来谈谈大脑的基本单元,也就是神经元,也是思考的基本构造,是如何组成其他心理结构的,又是如何形成不同脑组织的,最终构建出了整个的大脑
-
And as a result of that, the achieving of octet stability via electron transfer tumbled to the idea of an ionic bond where one atom donates an electron completely to the other atom, sort of like servanthood.
有了他们，也就是形成八隅体的稳定结构,通过电子的扰动形成理想的离子键,这儿一个原子完全将一个电子,给另一个原子，有点像奴仆关系。
-
Well instead of forming droplets like fat they arrange in a very particular way, they form these structures that are called self-assembled structures because they occur naturally, because of properties of the lipids.
它们不是像脂肪一样形成液滴,而会细致地排列起来,它们形成的结构名为,自组装结构,因为它们能够自然生成,这归功于这种脂质的特性
-
I do want to talk about one important subject which you might not have thought too much about and that's lipids, because lipids are so important to the structure of the body because they make up the membranes that form the cells that are the fundamental units.
我的确想要讨论一个重要的主题,这个主题也许你们都没有深入思考过,那就是关于脂类的问题,脂类对身体结构形成十分重要,它是组成细胞膜的基本单位,而细胞膜能够维持细胞形态
-
So, that's his gift to us: the Lewis structure, and the idea that you could share electrons and form a covalent bond.
这就Lewis给我们的礼物，Lewis结构，你能够通过公用电子,形成共价键。
-
Estrogen can combine with this receptor to form a new sort of unit which interacts with DNA.
雌激素能够与受体相结合,形成一个新结构单位与DNA相互作用
-
They will reform their natural structure, and for DNA that means forming double helixes.
它们将重新形成原本的结构,对于DNA来说,就是重新形成DNA双螺旋
-
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 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
-
That's because you have to satisfy this base pair matching in order to have hydrogen bonding in each of the struts of the ladder in order to form a stable structure.
NA双链要满足互补配对原则,以使碱基对之间,形成氢键,从而形成稳定的双链结构
