Every time a cell divides, its DNA is duplicated so that the two daughter cells have the same genetic material as their parent. This means that, millions of times a day, a biochemical wonder takes ...
A discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...
Researchers at the MRC Laboratory of Medical Sciences (LMS) and collaborators have uncovered one of the earliest steps in DNA replication: the moment a cell first opens its DNA to begin making a copy ...

DNA from a human brain gene has turned up in a virus
Unrelated virus. (Heather Davies/SPL/Getty Images) Some pieces of our DNA can copy themselves into new locations. Copies derived from one gene active in human brain cells appear to have taken that ...
A new discovery by researchers at the RIKEN Center for Biosystems Dynamics (BDR) in Japan upends decades of assumptions regarding DNA replication. Led by Ichiro Hiratani and colleagues, the ...

New research in The FEBS Journal links mitochondrial DNA copy number in cancer cells to mutational load, tumor growth gene expression, and chemotherapy response, suggesting mtDNA may shape cancer ...
Johns Hopkins Kimmel Cancer Center scientists report data from a new study providing evidence that random, unpredictable DNA copying "mistakes" account for nearly two-thirds of the mutations that ...
The ATR–ATRIP kinase complex safeguards genome integrity by coordinating cellular responses to DNA damage and replication stress. Two recent cryo-EM studies resolve the structural basis of ATR–ATRIP ...
DNA replication in eukaryotic cells is a highly coordinated, multi-step process that ensures precise duplication of the genome prior to cell division. In late mitosis and early G1 phase, the Origin ...
Real image of DNA molecules being copied in human cells, visualized by immunofluorescence microscopy. The yellow arrows mark where replication begins, and the white arrows indicate the direction in ...
