Thymine dimer คือ
WebbThe initial step is usually the detection of a damage spot, a thymine dimer for instance. Subsequently, the dimer is either repaired, or completely removed. Photolyase is an enzyme that detects the dimer site by binding to it and then catalyses the splitting of the dimer into the original pyrimidine bases (Figure 2). ...

WebbIn the eukaryotic system, the thymine dimers are repaired by photoreactivation. This repair system breaks the Thymine-Thymine dimer by involving light. It is the primary repair mechanism in eukaryotes. Therefore, the correct answer is (e). Please note that: Option (a) is incorrect as the small lesions are excised or removed by base excision repair.
