Molecular choreography of primer synthesis by the eukaryotic Pol α-primase
Nature Communications, 2023 The eukaryotic polymerase α (Pol α) synthesizes an RNA-DNA hybrid primer of 20–30 nucleotides. Pol α is composed of Pol1, Pol12, Primase 1 (Pri1), and Pri2. Pol1 and Pri1 contain the DNA polymerase and RNA primase activities, respectively.

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.

Replicative DNA Polymerases [PDF]
Cold Spring Harbor Perspectives in Biology, 2013 In 1959, Arthur Kornberg was awarded the Nobel Prize for his work on the principles by which DNA is duplicated by DNA polymerases. Since then, it has been confirmed in all branches of life that replicative DNA polymerases require a single-stranded template to build a complementary strand, but they cannot start a new DNA strand de novo.

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

DNA Replication Fidelity [PDF]
Journal of Biological Chemistry, 1992 ▪ Abstract DNA replication fidelity is a key determinant of genome stability and is central to the evolution of species and to the origins of human diseases. Here we review our current understanding of replication fidelity, with emphasis on structural and biochemical studies of DNA polymerases that provide new insights into the importance of hydrogen ...

Cold Spring Harbor Perspectives in Biology, 2013 The onset of genomic DNA synthesis requires precise interactions of specialized initiator proteins with DNA at sites where the replication machinery can be loaded. These sites, defined as replication origins, are found at a few unique locations in all of the prokaryotic chromosomes examined so far.

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.
