Now the bases, and you don't need to memorize the structures of these I'm going - I'm describing the whole molecule to you in its molecular detail and then we're going to simplify it down to a version that we can talk about more easily.

现在讲碱基,你不需要记住这些结构,我将给你们详述整个分子,的结构细节,然后我们把它简化为一个模板,使我们更容易讨论

We don't need to really talk about all the molecular detail in order to completely describe a DNA or an RNA molecule because these structures repeat themselves.

我们在完整的描述一个DNA或RNA时,不需要说明,分子上的每一个细节,因为它们的结构都是重复的

The whole structure of a DNA molecule looks like this, going back to a more cartoon version like I showed you before but adding some detail onto it now.

NA分子的全部结构都和,刚才的卡通模型上差不多,但细节更为丰富

That's what I want to do for the first few minutes of the lecture here is tell you a little bit about the details of the structure and how molecules fit into this image of DNA that's already very familiar to you.

这是我想要,在这节课最初几分钟告诉你们的,有关DNA结构的一些细节,DNA分子结构与这个卡通模型如此一致,对你们来说很熟悉
