A research group at the University of Bologna has identified, for the first time, the specific location and genomic context where DNA breaks occur due to the inhibition of the topoisomerase I, a ...

Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic ...

For almost 60 years, scientists have tried to understand why DNA doesn’t replicate wildly and uncontrollably every time a cell divides – which they need to do constantly. Without this process, we ...

Every day, billions of cells in your body divide, helping to replace old and injured cells with new ones. And each time this happens, your entire genetic library—your genome, which totals more than 3 ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...

A study headed by researchers at NYU Langone Health has found that herpes simplex virus 1 (HSV-1) partially liquifies the tightly packed, gel-like interior of human cell nuclei to help copy itself ...

When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting that involves construction of spindles to carefully separate the DNA after ...

"If it ain't broke, don't fix it," goes the old adage, which Rice University professor James Chappell completely ignored in a recent Nature Communications publication. In the study, Chappell describes ...

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

A new, nano-scale look at how the SARS-CoV-2 virus replicates in cells may offer greater precision in drug development, a Stanford University team reports in Nature Communications. Using advanced ...
