Expression of catalytic mutants of the mtDNA helicase Twinkle and polymerase POLG causes distinct replication stalling phenotypes. [PDF]
, 2007 The mechanism of mitochondrial DNA replication is a subject of intense debate. One model proposes a strand-asynchronous replication in which both strands of the circular genome are replicated semi-independently while the other model proposes both a ...

Cohesin causes replicative DNA damage by trapping DNA topological stress [PDF]
, 2020 DNA topological stress inhibits DNA replication fork (RF) progression and contributes to DNA replication stress. In Saccharomyces cerevisiae, we demonstrate that centromeric DNA and the rDNA array are especially vulnerable to DNA topological stress ...

The Swr1 chromatin-remodeling complex prevents genome instability induced by replication fork progression defects. [PDF]
, 2018 Genome instability is associated with tumorigenesis. Here, we identify a role for the histone Htz1, which is deposited by the Swr1 chromatin-remodeling complex (SWR-C), in preventing genome instability in the absence of the replication fork/replication ...

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

Damage-induced phosphorylation of Sld3 is important to block late origin firing. [PDF]
, 2010 Origins of replication are activated throughout the S phase of the cell cycle such that some origins fire early and others fire late to ensure that each chromosome is completely replicated in a timely fashion.

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.

Identification of Epstein-Barr virus replication proteins in Burkitt’s lymphoma cells [PDF]
, 2015 The working model to describe the mechanisms used to replicate the cancer-associated virus Epstein-Barr virus (EBV) is partly derived from comparisons with other members of the Herpes virus family.

PLOS Genetics, 2019 In all kingdoms of life, DNA is used to encode hereditary information. Propagation of the genetic material between generations requires timely and accurate duplication of DNA by semiconservative replication prior to cell division to ensure each daughter cell receives the full complement of chromosomes.

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 ...
