Personally I don't hear any but lots of my friends say they do. I obviously just hear silence but if you hear a ringing when there not plugged then I'd visit a doctor :D
Hey there! The sides of DNA have rails, or the sides of them that keep them together- and what's amazing is you can't even see it. They're made of sugar (deoxyribose) and phosphate molecules. They alternate, so sugar, phosphate and so on. Hope this helps!
