生物化学家将这套系统称之为中心法则(central dogma)：以长链核酸聚合物形式存在的DNA是遗传物质，它储存着每种蛋白质设计的数据记录。

Biochemists call it the central dogma: Genetic material, in the form of a long nucleic acid polymer called DNA, stores a digital record of every protein's design.

The nucleotide has a directionality, there's an up and a down to it and it's going to turn out the chain that's formed by polymerizing these has a directionality as well and that's important in defining the structure.

核苷酸有方向性,有上端和下端,核苷酸长链,是由核苷酸沿一个特定方向聚合而成的,这在定义结构时很重要
