When these nucleotides get polymerized to form a long DNA molecule they all get polymerized in exactly the same way, the chemistry is the same.

当这些核苷酸多聚化,形成一条长链DNA分子时,它们的聚合方式和,化学结构都完全相同

We'll talk about some chemistry today, what DNA molecules are like, why they have the behavior that they do, and you need to understand this in order to understand how you manipulate DNA.

今天我们会谈到一些化学结构,比如DNA分子的形态,它们为什么会以这种形态存在,你必须先掌握这些,才能理解如何操控DNA
