Biology textbooks are full of drawings of DNA, but none of those show what DNA actually looks like. Sure, they’re good models for understanding how DNA works, but inside of real cells, it’s a whole lot more interesting. Learn why we can’t look directly at DNA, and find out how DNA is actually packed inside cells.
