Answer:

Yes! Here is your answer!

Explanation:

UV-B causes damage at the molecular level to the fundamental building block of life— deoxyribonucleic acid (DNA). DNA readily absorbs UV-B radiation, which commonly changes the shape of the molecule in one of several ways.

UV-B radiation has been shown to be harmful to living organisms, damaging DNA, proteins, lipids and membranes. Plants, which use sunlight for photosynthesis and are unable to avoid exposure to enhanced levels of UV-B radiation, are at risk.
