DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave.

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic ...

Researchers at The Institute of Cancer Research, London identified the CIP2A–TOPBP1 complex as a master regulator of DNA repair during mitosis, coordinating backup pathways that protect chromosomes ...

Our genes contain all the instructions our body needs to function, but their expression must be finely regulated to guarantee that each cell performs its role optimally. This is where DNA and RNA ...

For decades, biology textbooks taught that DNA’s story could be told with a single image: two elegant strands twisting in a ...

Researchers from Karolinska Institutet have discovered how mammalian cells prevent the gradual buildup of harmful mutations in mitochondrial DNA, the small but vital genome that powers every cell. The ...

The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that ...

Scientists have recently been learning more about the importance of small bits of circular genetic material known as extrachromosomal DNA (ecDNA). These little circles of DNA can hitch a ride with ...

It has been claimed that because most of our DNA is active, it must be important, but now human-plant hybrid cells have been ...
