1. What changes in the DNA molecule occur under the influence of UV radiation?
2. What type of repairation corrects such damage? Schematic depict and explain.
The DNA molecule absorbs the UV light that results in the formation of the thymine dimers.
In humans, the base excision repair mechanism is used for this purpose. Following are the steps of this repair mechanism.
