_____ radiation excites atoms to a higher energy state within molecules such as DNA that then leads to the formation of pyrimidine dimers.

Question

Quizplus · Accepted Answer

Ultraviolet radiation is known to excite atoms to a higher energy state within molecules such as DNA, leading to the formation of pyrimidine dimers. Infrared radiation does not have sufficient energy to cause such molecular changes. Gamma radiation and particle radiation are both ionizing and can cause damage to DNA, but they do not specifically lead to the formation of pyrimidine dimers like UV radiation does.
