The formation of a covalent bond between two adjacent thymines is caused by
A) X-rays.
B) alkylating agents.
C) UV radiation.
D) microwave radiation.
E) heat.

Question

Quizplus · Accepted Answer

The formation of a covalent bond between two adjacent thymines, known as a thymine dimer, is primarily caused by UV radiation. UV radiation can cause the electrons in the thymines' chemical bonds to move, resulting in the formation of a covalent bond between adjacent thymines. This can disrupt the normal functioning of DNA and potentially cause mutations or other DNA damage.
