Damage caused by UV light leading to thymine dimers is corrected during photorepair by the enzyme ______. Multiple choice question.
Answer:
photorepair
Explanation:
Damage caused by UV light leading to thymine dimers is corrected during photorepair by the enzyme photoreactivation called as PRE. Thymine dimers are a problem leading to skin cancer in future.
What happens when the thymine dimer are not repaired ?If the thymine dimers are not repaired then it will lead to a condition of mispairing in DNA , transcription blocking.
It will lead to a condition of multiple growth of cells called as tumor where if uncontrolled UV exposure condition takes place then it will lead to skin cancer and is not curable if deadly stages comes up.
PRE enzyme in the presence of blue light breaks up the dimers and again restores the condition.
Therefore, DNA photolyase is the enzyme which stores energy and breaks the covalent bonds between the thymine dimer and restores the structures.
