Question

Quizplus · Accepted Answer

Quarks are subatomic particles that make up protons and neutrons, but not electrons, glucose molecules, or DNA. Neutrons and protons are made up of quarks, while electrons are leptons and do not contain any quarks. Glucose molecules and DNA are made up of atoms, which in turn contain protons and neutrons made up of quarks, but the overall structures themselves do not contain quarks.
