The discovery of Hoogsteen base pairs, an alternative pairing mode to the canonical Watson–Crick structure, has significantly broadened our understanding of DNA dynamics. This conformation, in which ...

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 ...

This image illustrates the chemical structures of the five main nucleobases found in DNA and RNA. The pyrimidines, thymine (DNA), uracil (RNA), and cytosine are shown on top while the purines, adenine ...
