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。反馈 收藏

It has a double stranded structure due to the specific base pairing of the nitrogenous bases.The DNA contains the genetic material for an organism. The DNA replication is a semi-conservative process, bidirectional and has high fidelity that occurs with series of reactions catalyzed by enzymes....
How DNA replication originates.(Frontiers in Biology: Chromosomes)Marx, Jean
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 ...
Eukaryotic DNA replication is a highly conserved process; the proteins and sequence of events that replicate animal genomes are remarkably similar to those... ML Depamphilis,JJ Blow,S Ghosh,... - 《Current Opinion in Cell Biology》 被引量: 314发表: 2006年 Rolling-circle replication of bacteri...
Greater understanding of how DNA replication is regulated opens new paths of research in genetics. When replication timing is altered—as it was in Gilbert and Sima's experiment—it can completely change how the genetic information of a cell is interpreted. ...
How long does it take for DNA to replicate? How can DNA be extracted from a plant cell? How does DNA sequencing work? How accurate is DNA replication? How does DNA electrophoresis work? How do cells repair single-stranded DNA? What could be the result of damaged DNA being replicated?
Chromosomes have noncoding DNA called what at then end of the chromosomes telomeres Every time a cell divides they lose a bit of the... telomeres Telomeres are usually long enough for how many cell divisions 50 Once the telomere is lost the cell usually ceases to... divide What is telomera...
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...
