Question: are atoms smaller than dna?
Answer: One nanometer (1 nm) is equal to 10-9 m or 0.000000001 m. A nanometer is 10 times smaller than the width of your DNA, and 10 times bigger than the size of an atom. Even though nanoscale is very small, it is at least 109 or 1,000,000,000 times bigger than a quark. Quarks are really, really, really small.
