(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。
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...

6) PROOFREAD: DNA Polymerase I proofreads new strand and backtracks to correct errors 5) JOINING NUCLEOTIDES: DNA ligase bonds those nucleotides together. The result is 2 identical DNA molecules. Each w/1 new strand & 1 old strand Called Semi-conservative replication (Continuous Replication) (P...
Now, in work done mainly in yeast, researchers are finding that this exquisite control of DNA replication is achieved by a complex of proteins interacting with specific short DNA sequences. They9ve also identified se...
How does DNA ultimately control the functioning of cells? How/why can mutations in DNA disrupt proper functioning? Explain how DNA is replicated bidirectionally. (a) List three problems that can occur during DNA replication. (b) How the body attempts to correct each problem?
(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...
When does DNA replication occur? Where does DNA replication occur? Learn about DNA polymerase and enzymes, DNA replication steps, and 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 ...
