Electromagnetic energy of which of the following wavelengths can damage DNA?
A) 300 micrometers
B) 300 centimeters
C) 300 nanometers
D) 300 millimeters
E) 300 meters

Question

Quizplus · Accepted Answer

Electromagnetic energy with shorter wavelengths, such as ultraviolet (UV) radiation, has enough energy to ionize atoms and molecules, which can lead to the formation of free radicals and cause damage to DNA. The wavelength of 300 nanometers falls within the UV-C range, which is known to be particularly damaging to DNA. The other wavelengths listed do not have enough energy to ionize atoms and are not known to cause DNA damage.
