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 ...

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

DNA–protein cross-links (DPCs) represent a severe form of DNA damage that can disrupt essential chromatin-based processes. Among them, DNA–histone cross-links (DHCs) occur frequently within ...

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

Nucleic acids are complex biological molecules that store and transmit genetic information in all living organisms. They are essential for the survival and reproduction of life on Earth. The two main ...

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 ...
