Vedclass · Answer

(B) Exposure to $UV$ radiation,particularly $UV-B$,causes the formation of pyrimidine dimers,most commonly thymine dimers,in $DNA$. This occurs because $UV$ light provides enough energy to form covalent bonds between adjacent thymine bases on the same strand of the $DNA$ molecule. These dimers distort the $DNA$ structure,which can lead to mutations during $DNA$ replication if not repaired by the cell's repair mechanisms.
