When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting ...

Cancer’s strongest gene switches push DNA into damaging overdrive, creating repeated breaks and repairs that may fuel tumor ...

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 ...

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 created a live-cell DNA sensor that reveals how damage appears and disappears inside living cells, capturing the entire repair sequence as it unfolds. Instead of freezing cells at ...

The story of life’s beginnings gets stranger when you look closely at viruses. These tiny entities seem to sit at the edge of biology.

A protein found in our cells has emerged as a secret weapon against biological aging, acting like a glue to repair damaged DNA and ward off neurological degeneration including that seen in motor ...

When a virus infects a bacterial cell, the viral genome is the first component to be fully injected into the cell, making it an ideal immune target. A bacterial enzyme anchored to the membrane ...

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 ...

Scientists are exploring DNA-based robots, tiny molecular machines that could one day navigate the body, deliver targeted therapies, and even build nanoscale technologies.

Scientists at Sanford Burnham Prebys Medical Discovery Institute and an international team of collaborators have defined a ...

The droppings contain DNA, he thought, and perhaps, even after rain washes them away, some DNA might remain. And if it does ...
