Free radicals
A) form because of radiation exposure.
B) form due to base analogs.
C) form when atoms have paired electrons.
D) are not reactive.
E) are incorporated into DNA instead of normal bases.

Question

Quizplus · Accepted Answer

Free radicals are highly reactive molecules that form due to radiation exposure, which can cause damage to DNA and other cellular components. Base analogs can also lead to DNA damage, but they do not directly form free radicals. Free radicals form when atoms or molecules have unpaired electrons, which makes them highly reactive and capable of damaging cellular components. Free radicals are not incorporated into DNA instead of normal bases.
