Semiconservative replication :The two strands of DNA double helix are separated, each strand serves as a template for the synthesis of a new complementary strand, producing two daughter molecules. Each daughter molecule has one parental strand and one newly synthesized strand.

半保留复制： DNA 生物合成时，母链 DNA 解开为两股单链，每股单链分别作为模板，以 dNTP(dATP 、 dGTP 、 dCTP 、 dTTP)为原料，按照碱基配对(A － T 、 G － C)规律与模板上的碱基配对，经依赖 DNA 的 DNA 聚合酶催化，合成一条与模板互补的新链，新形成的两个子代 DNA 与亲代 DNA 碱基序列一致，子代 DNA 分子中一股单链是从亲代完整地接受过来，另一股单链是新合成的，故称为半保留复制。
