See conservative, semiconservative, and dispersive DNA replication models. Find out how the Meselson and Stahl experiment identifies the correct replication model. Related to this Question How is DNA replication accurate? How does the structure of DNA result in accurate replication?
(在真核细胞中(如酵母),DNA复制的如何起始的)相关知识点: 试题来源: 解析 答:酵母的复制起始位点称为自主复制序列(ARS),由一段保守的150bp的序列组成,富含AT碱基对。该区域也被称为A元件(如图)。起始位点识别复合体(ORC)识别A元件,然后依次将解旋酶,引物酶,DNA聚合酶等募集到复制器上。DNA复制进入延伸阶段。
Since DNA is the universal carrier of genetic information, it stands to reason that unicellular organisms as well as the individual cells of multicellular organisms must be able to faithfully replicate their DNA content prior to the production of daughter organisms or daughter cells. DNA replication ...

(a)Compare between DNA replication and transcription.Similarities1. Both involve unwinding of the double helix DNA;2.Both involve breaking of the weak hydrogen bonds between complementarbases;3.Both involve formation of phosphodiester bonds between neighbouring nucleotides;4.Both involve aligning free nucl...
DNA polymerase will subsequently fill in the correct nucleotide. This repair mechanism can also be used to fix depurination (a missing purine base), thus eliminating the need for glycosylases (Figure 2; IIIa). b) Nucleotide Excision Repair (NER) The heterodimer DDB (DNA Damage-Binding) is ...
DNA stores all of the information necessary for life phenomena, and a cell transmits its own genetic information to two daughter cells through DNA replication and cell division. Replication stress can be caused by extracellular and intracellular sources
