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

Researchers have identified the specific structural loops in G-quadruplex DNA that allow it to act as a chaperone, preventing ...

In the middle of the 20th century, accumulating data suggested that DNA carries life’s genetic information. Biochemists around the world raced to determine its structure. The competition led to some ...

The first crystal structure of an alternative DNA shape from the insulin gene has been revealed by a UCL-led research team. DNA is widely accepted to be formed of two strands that wind around one ...

Chemical structure of guanine, showing its double-ring purine structure and the functional groups involved in hydrogen bonding with cytosine. (Image: Public Domain) Guanine has the chemical formula ...

This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...

What scientists long believed were knots in DNA may actually be persistent twists formed during nanopore analysis, revealing ...
