(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。
All cells contain DNA, which encodes all the genetic information of an organism. The DNA in each cell can be transmitted to future generations, that is, the genetic material is heritable. There are different ways to describe and classify organisms. For example: Unicellular organisms versus ...

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 ...
Understand how DNA is replicated. Learn why DNA replicates, when DNA replicates, and how DNA replication works. Get an overview of the rates of replication of different cells. Related to this Question How accurate is DNA replication? How does the structure of DNA result in accurate replication?
Origin of Replication: DNA replication does not start at random locations but at particular sites, called the origins of replication. A unit of DNA in which an individual act of replication occurs is called a replicon. Replicon can be linear or circular. Replication in bacterial cells is monore...
When does DNA replication occur? Where does DNA replication occur? Learn about DNA polymerase and enzymes, DNA replication steps, and DNA...
DNA Replication Essential Question: How do enzymes help ensure DNA is copied correctly? 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 polymerases were named for their function of catalysing DNA replication, a process that is necessary for growth and propagation of life. DNA involving Watson–Crick base-pairing can be synthesized with high fidelity, the structural and mechanistic origins of which have been investigated for many...
Under these experimental conditions, they found that, when ATAD5 level is reduced, cells cannot resume DNA replication stalled by replication stress, but increases genome instability such as intracellular chromosome breakage and micronucleated reticulocytes in mouse blood. This means that ATAD5 contribute...
