Question
Which of the following is an example of a mutagen?Group of answer choicesradiationX-rayUV radiationsome organic chemicalsall of these
Solution
All of these are examples of a mutagen.
Here's why:
-
Radiation: High-energy radiation, such as that released by radioactive substances, can cause mutations by breaking the covalent bonds in DNA.
-
X-ray: X-rays are a type of ionizing radiation that can cause mutations in DNA.
-
UV radiation: Ultraviolet (UV) radiation, particularly UV-B radiation, can cause mutations by leading to the formation of pyrimidine dimers in DNA.
-
Some organic chemicals: Certain organic chemicals, such as polycyclic aromatic hydrocarbons, can intercalate into DNA and cause mutations.
So, all of these - radiation, X-ray, UV radiation, and some organic chemicals - are examples of mutagens.
