And the dialogue ends with one of the great moving death scenes in western civilization and as Plato says-- let's get the quote here exactly right-- "Of all those we have known, he was the best and also the wisest and the most upright."

然后对话以一个,西方文明史上最伟大感人的死亡场景结束,用柏拉图的话说,让我们引用的更准确些,在我们所知的所有人中,他是最好,最有智慧,最正直的人

One is that there are two backbones right here in the light blue, so this would be the upright parts of the ladder that are twisted.

其一是浅蓝色所代表的两条主链,这是构成,扭曲梯子的垂直部分

It's the phosphate and the pentose that make up the backbone - that make up the upright struts of the ladder and it's the bases that make up the connecting struts, so the bases are the colors.

磷酸基和戊糖,共同构成了主链,主链又构成了梯子上下的支柱,而碱基,则构成连接支柱的梯阶,碱基是用各种颜色表示的

This represents the upright struts on a ladder that I showed you before, it represents this backbone that's shown by - that's formed by polymerizing the pentose's together through phosphate's always going 5' to 3', 5' to 3'.

线条代表梯子,上下的支柱 之前给你们演示过,代表由多聚戊糖分子,通过磷酸基从5'端向3'端方向,连接起来的主链

Now DNA is a double helix and I've only shown you one part of the helix, right? I've shown you one upright strut and a base hanging off of it, but it forms a double helix because complementary strands of DNA strongly associate with one another and that's a very stable structure.

NA是双螺旋,我只是给你们讲了螺旋的一边,我给你们演示,一条链的支柱及碱基团,但其能构成双螺旋,是因为DNA是完全互补的两条链,彼此之间结合紧密,结构异常稳定
