解析 答:DNA在进行复制的时候链间氢键断裂,双链解旋分开,每条链作为模板在其上合成互补链,经过一系列酶(DNA聚合酶、解旋酶、链接酶等)的作用生成两个新的DNA分子。子代DNA分子其中的一条链来自亲代DNA,另一条连链是新合成的,这种方式称半保留复制。
3.4.1 Explain DNA replication in terms of unwinding the double helix and separation of the strands by helicase, followed by formation of the new complementary strands by DNA polymerase. DNA replication is semi-conservative as both of the DNA molecules produced are formed from an old strand and ...
To determine who proposed the semiconservative replication of DNA, we can follow these steps:1. Understand Semiconservative Replication: - Semiconservative replication is a method of DNA replication where each of the two st
