Gluons 101

Is my understanding correct that gluons are the force carrier particle of the strong nuclear force?

Do gluons hold together quarks? Or do gluons hold together atomic nuclei?

Thanks,
Glenn

Gluons, as mediators of the strong interaction, bind together quarks into hadrons. In atoms, they also bind nucleons (protons, neutrons) into nuclei.
