The dynamics of replication licensing in live Caenorhabditis elegans embryos [PDF]
, 2012 Accurate DNA replication requires proper regulation of replication licensing, which entails loading MCM-2-7 onto replication origins. In this paper, we provide the first comprehensive view of replication licensing in vivo, using video microscopy of ...

The elusive determinants of replication origins [PDF]
EMBO reports, 2007 Despite their central role in maintaining genetic integrity during cell division, there is still considerable uncertainty about how DNA sequences are selected to be replication origins in eukaryotes (DePamphilis, 1999; Gilbert, 2001; Machida et al , 2005). The budding yeast Saccharomyces cerevisiae uses a limited set of efficient origins, each of which

New stopping criteria for segmenting DNA sequences [PDF]
, 2001 We propose a solution on the stopping criterion in segmenting inhomogeneous DNA sequences with complex statistical patterns. This new stopping criterion is based on Bayesian Information Criterion (BIC) in the model selection framework. When this stopping

Prediction of Saccharomyces cerevisiae replication origins [PDF]
Genome Biology, 2004 Autonomously replicating sequences (ARSs) function as replication origins in Saccharomyces cerevisiae. ARSs contain the 17 bp ARS consensus sequence (ACS), which binds the origin recognition complex. The yeast genome contains more than 10,000 ACS matches, but there are only a few hundred origins, and little flanking sequence similarity has been found ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction We developed MedSupport, a multilevel medication adherence intervention designed to address root barriers to medication adherence. This study sought to explore the feasibility and acceptability of the MedSupport intervention strategies to support a future full‐scale randomized controlled trial.

Dynamic distribution of SeqA protein across the chromosome of Escherichia coli K-12 [PDF]
, 2010 The bacterial SeqA protein binds to hemi-methylated GATC sequences that arise in newly synthesized DNA upon passage of the replication machinery. In Escherichia coli K-12, the single replication origin oriC is a well-characterized target for SeqA, which ...

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

The replication machinery of LUCA: common origin of DNA replication and transcription
BMC Biology, 2020 Origin of DNA replication is an enigma because the replicative DNA polymerases (DNAPs) are not homologous among the three domains of life, Bacteria, Archaea, and Eukarya. The homology between the archaeal replicative DNAP (PolD) and the large subunits of

Horizontal transfer between loose compartments stabilizes replication of fragmented ribozymes
, 2019 The emergence of replicases that can replicate themselves is a central issue in the origin of life. Recent experiments suggest that such replicases can be realized if an RNA polymerase ribozyme is divided into fragments short enough to be replicable by ...
