At the beginning of replication, DNA is unzipped by helicase (yellow). Then primase (red) creates the first few base pairs that DNA polymerase (blue) will recognize, before it begins replication.DNA replicationScitable

On the basis of these observations and positional and orientational relationships between the Chi and the Ter sequences, we propose a model in which the DNA replication fork blocked at the Ter site provides an entrance for the RecBCD enzyme into duplex DNA. 展开 ...
A cell can be thought of as a highly sophisticated micro factory: in a pool of billions of molecules - metabolites, structural proteins, enzymes, oligonucleotides - multi-subunit complexes assemble to perform a large number of basic cellular tasks, such as DNA replication, RNA/protein synthesis ...
aIn order to initiate the process of replication of the DNA, two informing sequence codes denominated primers are required which promote the beginning and reversion of the reaction of the polymerase (RNA-pol) at particular locations of the genome. 为了创始脱氧核糖核酸的复制的过程,要求二通知的序列...
The correct Answer is:B (b) : In eukaryotes, the replication of DNA takes place at S-phase of the cell cycle. The replication of DNA takes and cell division cycle should be coordinated. A failure in cell division after DNA and only one of the strands is copied into RNA. Show More ...
In eukaryotes, DNA compacts into chromatin through nucleosomes1,2. Replication of the eukaryotic genome must be coupled to the transmission of the epigenome encoded in the chromatin3,4. Here we report cryo-electron microscopy structures of yeast (Sacchar
In mice, the first round of DNA replication occurs in fertilized eggs (1-cell embryos), while the onset of zygotic gene transcription begins 20 hours after fertilization, a time that normally coincides with formation of a 2-cell embryo. One approach to investigating the mechanisms that control ...
We have developed an in vitro system that supports the replication of natural DNA templates of the autonomous parvovirus minute virus of mice (MVM). MVM virion DNA, a single-stranded molecule bracketed by short, terminal, self-complementary sequences, is converted into double-stranded replicative-...
