Nucleosome-directed replication origin licensing independent of a consensus DNA sequence
Nature Communications, 2022 Most eukaryotes do not use a consensus DNA sequence as binding sites for the origin recognition complex (ORC) to initiate DNA replication, however budding yeast do. Here the authors show S. cerevisiae ORC can bind nucleosomes near nucleosome-free regions

Both Chromosome Decondensation and Condensation Are Dependent on DNA Replication in C.elegans Embryos [PDF]
, 2015 During cell division, chromatin alternates between a condensed state to facilitate chromosome segregation and a decondensed form when DNA replicates.

DNAReplication: a database of information and resources for the eukaryotic DNA replication community [PDF]
, 2009 DNAReplication (at http://www.dnareplication.net) has been set up as a freely available single resource to facilitate access to information on eukaryotic DNA replication.

Quantitative sensing and signalling of single-stranded DNA during the DNA damage response
Nature Communications, 2019 DNA damage triggers checkpoint signalling mechanisms. Here the authors reveal differential phosphorylation of targets of the Mec1-Ddc2 checkpoint kinase by analyzing the effect of quantitatively different ssDNA signals.

Chromatin and DNA Replication [PDF]
Cold Spring Harbor Perspectives in Biology, 2013 The size of a eukaryotic genome presents a unique challenge to the cell: package and organize the DNA to fit within the confines of the nucleus while at the same time ensuring sufficient dynamics to allow access to specific sequences and features such as genes and regulatory elements.

SARS-CoV-2: from its discovery to genome structure, transcription, and replication
Cell & Bioscience, 2021 SARS-CoV-2 is an extremely contagious respiratory virus causing adult atypical pneumonia COVID-19 with severe acute respiratory syndrome (SARS). SARS-CoV-2 has a single-stranded, positive-sense RNA (+RNA) genome of ~ 29.9 kb and exhibits significant ...

eLife, 2017 DNA double strand breaks (DSBs) can be repaired by either recombination-based or direct ligation-based mechanisms. Pathway choice is made at the level of DNA end resection, a nucleolytic processing step, which primes DSBs for repair by recombination ...

Attenuation of reverse transcriptase facilitates SAMHD1 restriction of HIV-1 in cycling cells
Retrovirology, 2023 Background SAMHD1 is a deoxynucleotide triphosphohydrolase that restricts replication of HIV-1 in differentiated leucocytes. HIV-1 is not restricted in cycling cells and it has been proposed that this is due to phosphorylation of SAMHD1 at T592 in these ...
