Reply to comment by padsley in Depictions of atomic nuclei often show distinct and individual protons and neutrons, is this accurate? by ZTYTHYZ

Question. Do the (valence) quarks in a proton or neutron in a nucleus stay part of that one proton/neutron? Or is there exchange of quarks between protons and neutrons? (Or is it unknown? Or is the question meaningless?)
