在合成新的DNA分子时，亲本分子所含的信息以极高的准确度传递给子代分子，它的每一条链均可作为合成另一条互补链的模板，从而产生两个与原来DNA相同的分子。即使是单链DNA分子．在其复制过程中也要先形成双键的复制型（RF式），再产生子代DNA。DNA的复制过程可概括为：（）双 When synthesizing a new DNA molecule, the information contained in the parent molecule is passed to the progeny molecule with a high degree of accuracy, and each of its chains can be used as a template for synthesizing another complementary strand, resulting in two identical to the original DNA. Molecules. Even single-stranded DNA molecules. In the process of its replication, it is also necessary to form a double bond (RF type) first, and then generate offspring DNA. The DNA replication process can be summarized as: () double
