The formation of a covalent bond between two adjacent thymines is caused by
A)mustard gas.
B)alkylating agents.
C)microwave radiation.
D)UV radiation.

Question

Quizplus · Accepted Answer

UV radiation is known to cause the formation of covalent bonds between adjacent thymine bases in DNA, leading to the formation of thymine dimers. This can result in genetic mutations and increase the risk of cancer. Mustard gas and alkylating agents can also damage DNA but do not specifically cause thymine dimers. Microwave radiation is not known to cause DNA damage.
