DNA replication is the process by which DNA is duplicated or copied prior to cell division, and which allows the daughter cell to retain a set of its own genetic material. During this process, the two DNA strands are unwound...
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: complementary pairingDNA structure told people somethingabout the replication, but not sufficient 3 models for replication 3 models for replication: Semiconservative model: old strands separate, copy & stay with the new strand Dispersive model: each strand is composed by short segments ...
General Features of DNA replication include: a. 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 exonuc...
Figure 1. Replication model. model is called semiconservative replication. The opening of the DNA produces two replication forks (see Figure 1), both of which will be the sites for replication. The forks will move in opposite directions relative to the replication machinery, with DNA replication ...

Figure 1. There were three models suggested for DNA replication. In the conservative model, parental DNA strands (blue) remained associated in one DNA molecule while new daughter strands (red) remained associated in newly formed DNA molecules. In the semiconservative model, parental strands separated...
Semiconservative DNA Replication 1. Watson and Crick DNA model implies a mechanism for replication: a. Unwind the DNA molecule. b. Separate the two strands. c. Make a complementary copy for each strand. 2 .Three possible models were proposed for DNA replication: a. Conservative model proposed ...
What is an antisense strand in DNA replication? Describe the Semiconservative model for DNA replication. What is the role of RNase H in DNA replication? A) How does DNA copy itself through the process of replication? B) What is meant by semiconservative replication?
Describe the steps involved in DNA replication for both the leading and lagging strands in a replication fork starting with the actions of helicase and topoisomerase. Describe the Semiconservative model for DNA replication. List and describe five steps in chromos...
