An international collaboration steered by David Cortez, Richard N. Armstrong, Ph.D. Chair for Innovation in Biochemistry, explored how cells tolerate DNA damage and genome instability—and they arrived ...
The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...
For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event for DNA to be the molecule that codes all life. A new study from King ...

Scientists just caught cells quietly copying their DNA but forgetting to split in two — leaving them with double the genetic material in a glitch now tied to cancer and agi…
A cell copies all six billion letters of its DNA, gears up to split, and then simply… doesn’t. It sits there, swollen with ...
Eukaryotic chromosomes replicate from multiple discrete loci termed origins of replication. These sites are first recognised by the origin recognition complex (ORC), which, together with Cdc6 and Cdt1 ...

A 3 mg melatonin pill before daytime sleep just boosted night shift workers’ DNA repair by 80% — the first trial built to test the link
Roughly 15 million Americans clock in for night shifts, and the World Health Organization’s cancer research arm has ...

Bacterial DNA replication is a highly coordinated process that ensures faithful genome duplication and cell division. Replication initiates at a single chromosomal origin (oriC) where multiple copies ...
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, ...
Within the nucleus of every cell are long strings of DNA, the code that holds all the information needed to make and control every cell within a living organism. DNA, which stands for deoxyribonucleic ...
As cells divide, they must copy all of their chromosomes once and only once, or chaos would ensue. How do they do it? By Amber Dance/Knowable Magazine Published Jul 7, 2023 6:00 PM EDT This article ...
DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave. Researchers have now mapped this hidden architecture in unprecedented detail, showing ...
