(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。

How DNA replication originates.(Frontiers in Biology: Chromosomes)Marx, Jean
This process is referred to as DNA replication. Therefore, DNA replication can be defined as the process in which double-stranded DNA gets duplicated. This process ensures that the two cells generated during binary division receive a complete copy of the DNA molecule, identical to the original ...
DNA replication is central to cell proliferation. Studies in the past six decades since the proposal of a semiconservative mode of DNA replication have confirmed the high degree of conservation of the basic machinery of DNA replication from prokaryotes to eukaryotes. However, the need for replication...
DNA is the genetic material of the cell and holds all the information necessary for life. During DNA replication, DNA is copied to form two identical molecules that can be used during cell division. Answer and Explanation:1 DNA replication is accurate because of the complementary pairing of nucl...
DNA or 2'-deoxyribonucleic acid contains the genetic material for an organism. Replication of DNA is an important process, especially in cell division. A new cell requires a new strand of DNA and DNA replication provides an identical copy of the genetic material to form a newly synthesized DNA...
How is DNA replication different from DNA transcription? In transcription, only a single DNA strand is used as a template to create a complementary strand of mRNA. In transcription, one of the two DNA strands is copied into DNA In transcription, a ...
Why does DNA replicate? Cells copy genetic information before cell division so that each new cell has a complete set of DNA DNA replication occurs in the nucleus…WHY?? DNA Template How does DNA replicate 1) UNWIND: Topoisomerase unwinds the coiled strands of DNA ...
How does a cell initiate DNA replication at an origin and then prevent a second round of replication at that same origin? How does the structure of DNA fit its function, especially as it relates to DNA replication? Explain the role of DNA polymerases in replication. ...
