The double strands of DNA are separated, which requires the DNA helicase to disassemble the original double stranded DNA. Where the double chain breaks down is called a replication fork. Two replication forks can generate a replication bubble. The chemical mechanism of DNA replication is that the ...
We show that totipotent cells of the early mouse embryo have slow DNA replication fork speed and that 2CLCs recapitulate this feature, suggesting that fork speed underlies the transition to a totipotent-like state. 2CLCs emerge concomitant with DNA replication and display changes in replication ...

Each of the four steps of DNA replication included in the instructional presentation was represented as a text slide, a simple 2D graphic, and a rich 3D graphic. Participants were middle grade girls (n = 21) attending a summer math and science program. Students’ eye movements were measured ...
(Maheshri et al., 2006). Multiple variations of the AAV directed-evolution process have since been utilized, but the overall strategy is similar. First, the capsid genes are randomly mutagenized, or mixed, to form a library of pooled capsid variants in the context of a replication-competent...
Second, cellular processes that entail the separation of the complementary strands, such as transcription and replication, generate a competition between the reconstitution of B-DNA through strand reannealing and the formation of alternative structures at repeat sequences, which may be occasionally ...
DNA replication, and cell cycle in the genes whose expression variation is associated with islands (Fig.4band Supplementary Data3), a conclusion confirmed by a Reactome analysis (Supplementary Fig.9). Noteworthy, these results were obtained when we analyzed the function of the human homologs not ...
(mutS,mutD, ormutT). The lack of a DNA repair system results in changes during replication in the genetic material entered into the strain; as a result, the target gene undergoes random mutations. A disadvantage of this method is that the modifiedE. colistrain quickly loses viability, ...
functions to replicate the nucleotide sequences encoding the heavy chain and/or the light chain of the antibody from the RNA replicon via the sub-genomic viral promoters. Such replication driven by the viral sub-genomic promoter using the viral non-structural proteins enhances the replication level...
