In eukaryotes, DNA replication begins with the binding of the six-subunit origin recognition complex (ORC) to the origins of DNA replication. ORC binds to the origin sites in an adenosine triphosphate-dependent manner and directs the assembly of the pre-replicative complex at the origins, thus ...
DNA replication in eukaryotes is a conserved system that only allows for DNA replication to occur once throughout each cell cycle. The replication of chromosomal DNA in eukaryotes is critical for the duplication of a cell and is required for the maintenance of the eukaryotic genome. Steps in ...
Eukaryotes also have a number of different linear chromosomes. The human genome has 3 billion base pairs per haploid set of chromosomes, and 6 billion base pairs are replicated during the S phase of the cell cycle. There are multiple origins of replication on each eukaryotic chromosome; humans ...
(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。
In eukaryotes, the origin recognition complex (ORC) is essential for replication licensing. Here, the authors report that a short motif within the intrinsically disordered region of the yeast Orc2 subunit plays an important role in regulating the licensing process. Yue Wu , Qiongdan Zhang & Yuan...

Initiation of DNA replication in eukaryotes begins with the binding of the origin recognition complex (ORC) to origins of replication during the G1 phase of the cell cycle. The ORC complex then serves as a platform for forming much more complicated pre-replicative complexes (pre-RCs). Formation...
