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.

WebbSuch treatment leads to selective production of thymine: thymine dimers in DNA. The DNA was melted and the renaturation rate was determined as a function of thymine dimer content and renaturation temperature. Under “normal” hybridization conditions little change in the renaturation rate was observed even when 30% of the thymine was dimerized. Webbสรุป - ง Dimer เทียบกับ FDP .
