A cell copies all six billion letters of its DNA, gears up to split, and then simply… doesn’t. It sits there, swollen with ...

In each cell of your body, DNA is stored in structures called chromosomes. When cells divide, these chromosomes are copied, ...

Researchers at the University of Bristol have caught DNA-copying enzymes generating long stretches of genetic code without any template to guide them, a behavior the team calls “doodling.” Published ...

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 ...

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 ...

In research published in Nature Structural & Molecular Biology, researchers from the University of Birmingham have found that transcription start sites (TSS) have a significant role in determining ...

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 ...

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 ...

Similar to the way DNA damage can contribute to human diseases such as cancer, it can also disrupt growth, development and ...

Live imaging of embryos at different stages. Chromosomes are labeled in magenta. 4-cell sister blastomeres are shown, along with 3D-reconstructed images of 2-to-4-cell and 4-to-8-cell divisions.
