Quizplus · Accepted Answer

Thymine dimers are removed by photoreactivation repair and excision repair. Photoreactivation repair uses light energy to break the covalent bonds between the thymine dimers, while excision repair involves the removal of the damaged DNA strand and repair using the undamaged strand as a template. SOS repair is not involved in repairing thymine dimers specifically.
