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 ...

In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

Scientists reveal a hidden second layer of human DNA, showing how genome folding controls genes and influences disease development.

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 ...
