TT dimer
Induction of Thymidine (T-T) Dimers by UV radiation

Thymidine Dimers are produced when adjacent thymidine residues are covalently linked by exposure to ultraviolet radiation. Covalent linkage may result in the dimer being replicated as a single base, which results in a frameshift mutation.
