DNAreplicationinprokaryotes 一、复制的起始 起始是复制中较为复杂的环节，在此过程中，各种酶和蛋白因子在复制起始点处装配引发体，形成复制叉并合成RNA引物 需要解决两个问题：1.DNA解开成单链，提供模板 2.形成引发体，合成引物，提供3-OH末端 原核生物的复制起始部位及解链 （此图有误需修改）（此图错误...

7.2 DNA replication 7.2.1 State that DNA replicationoccursin a 5‘ → 3‘ direction. DNA replication occurs in a 5'→3' direction. 7.2.2 Explain the process of DNA replication in prokaryotes, including the role of enzymes (helicase, DNA polymerase, RNA primase and DNA ligase), Okazaki ...
DNA Replication: DNA replication is the process in which DNA is copied. DNA replication is a semiconservative process, meaning the parent strand is used as the template strand. Answer and Explanation:1 The steps of DNA replication in prokaryotes is as follows: ...
DNA Replication in Prokaryotes and Eukaryotes DNA replication is a process in which the genetic material of a cell, in this case, the DNA makes an exact copy of itself and the process is controlled by the enzyme DNA polymerase. In mammals, the rate of replication is around 50 nucleotides pe...

regulation compared to prokaryotes. A single bidirectional replication origin is sufficient to direct all DNA synthesis in prokaryotes. In contrast, eukaryotic chromosome replication requires the orchestration of multiple DNA replication origins to ensure that each DNA polymer, irrespective of its size in ...
