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 ...

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 ...

Mitochondrial deoxyribonucleic acid (mtDNA) is essential for cellular energy production and overall cell function. Abnormalities in mtDNA are linked to various diseases and are also implicated in ...

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, ...

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

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 ...

"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 ...

Michael is a junior at Fordham College Lincoln Center majoring in Natural Sciences with focus on Cell and Molecular Biology ...

A representative figure showing that HELQ-deficient cells fail to undergo normal fork slowing after MMC (a crosslinking agent) treatment, consistent with defective fork reversal. Every time a cell ...
