DNA replication is described as semiconservative, because each DNA molecule is made up of one old conserved strand of DNA and one new one. When a gene is switched on, an enzyme called RNA polymerase attaches to the start of the gene. It moves along the DNA making a strand of messenger ...
何谓DNA的半保留复制(semiconservative replication)?相关知识点: 试题来源: 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...

DNA Replication (Updated) Why is replication called Semiconservative? DNA replication is semi-conservativebecause each helix that is created contains one strand from the helix from which it was copied. The replication of one helix results in two daughter helices each of which contains one of the ...
DNA replication is semiconservative b. DNA replication is bi-directional c. DNA replication is semi-discontinuous 2. Enzymes in DNA replication include: a. DNA polymerases's multiple activities: polymerization of nucleotides, proofreading DNA, and exonuclease activity b. The enzyme, reverse transcriptas...

Replication in Prokaryotes: Replication is semiconservative: The parent DNA has two strands complementary to each other. Both the strands undergo simultaneous replication to produce two daughter molecules. Each one of the newly synthesized DNA has one-half of the parental DNA (one strand from or...
1、DNA replication (复制),1. Overview,A parental duplex of DNA is replicated to form two daughter duplexes, each of which consists of one parental strand and one (newly synthesized) daughter strand.This behavior is called semiconservative (半保留) replication.,1.1 concepts,The replicon (复制子...
