Ultraviolet (UV) rays from sunlight can cause DNA damage that leads to skin aging and cancer. Fortunately, our bodies have a ...

Hoogsteen base pairing: An alternative configuration to Watson–Crick pairing in DNA, involving a 180° rotation of the purine base that results in unique hydrogen bonding and structural orientation.

A base pair is a fundamental unit of double-stranded nucleic acids, such as DNA and RNA.It consists of two complementary nucleobases bound to each other by hydrogen bonds. The base pairing rules state ...

This DNA is distinguished by a base, found nowhere else, that undergoes a different type of base pairing. Diaminopurine, awkwardly abbreviated as Z, is structurally similar to the adenine (A ...
