DNA is, thus, rapid.DNA replicationmust also be extremely accurate to avoid deleterious mutations in thegeneticinformation. The error frequency duringE. colireplication is estimated to be 10−7, or one mismatch per 107bp replicated, before additional correction by the mismatch-repair system. ...
2g,h). We conclude that 2CLC emergence occurs concomitant with DNA replication and that entry into the S-phase is key for this reprogramming. Fig. 2: Emergence of 2CLCs occurs together with or after DNA replication. a, Strategy to evaluate 2CLC emergence during the S-phase. b, After ...
To ensure that DNA is replicated precisely once per cell cycle, eukaryotic DNA replication initiation involves two steps, with each being restricted to different cell cycle phases1. In the first step (origin licensing), replicative helicase precursors are loaded at origins of replication2; in the ...
This creates major problems in synchronization. Synthesis at each origin must be coordinated to make sure that each chromosome is completely replicated. Conversely, each origin must initiate once and once only during each replication cycle in order to avoid duplication of DNA segments that have ...
In addition, accurate DNA duplication is an essential step carried out by a complex DNA replication machinery but errors during this process can also compromise genomic integrity. For example, damaged DNA, which cannot be replicated by the high fidelity replicative DNA polymerases, can lead to stall...

This rule applies when the overridden site is associated with the wireless controller's network profiles and is managed by the same wireless controller. Table 2. New and Changed Features for Cisco DNA Center, Release 2.3.5.5 FeatureDescription ...
The molecular weight of the recovered DNA depends on the shearing forces applied during homogenization. If recovery of high molecular weight DNA is desired, use a loosely fitting homogenizer in the initial homogenization step of the RNA Isolation P...
Using a live single-cell imaging approach, we show that DNA damage accrued during S-phase, in non-transformed cycling cells, results in heterogeneity in p21 levels that is p53-dependent. We find that p21 accumulates during mother G2- and daughter G1-phases, where it modulates the proliferatio...
In many eukaryotes, sequencing of cells at different stages of the cell cycle has been used to profile DNA replication timing, which measures the relative time that different genomic regions are replicated during S phase (reviewed in1). This replication-timing program is highly reproducible across ...
