Dimer

In a homodimer the two subunits are identical, and in a heterodimer they differ (though they are often still very similar in structure).

Trans-dimer synthesis
A process which permits nucleotides to be inserted opposite a pyrimidine dimer. Because this process is not based upon complementary base pairing, the wrong base pairs may be inserted, resulting in a mutation.
