It is now believed that protons and neutrons ( which constitute nucleI of ordinary matter ) are themselves built out of more elementary units called quarks. A proton and a neutron consist of three quarks each. Two types of quarks, the so called 'up' quark ( denoted by 'u') and 'down' quark ( denoted by 'd') of charge `(2)/(3) e ` and `(-1)/(3) e` respectively , together with electrons build up ordinary matter. Suggest a possible quark composition of a proton and a neutron.

It is now established that protons and neutrons are themselves built out of more elementary units called quarks a proton and a neutron consist of three quarks each. Two types of quarks , the so called 'up' quark, (denoted by U) of charge + (2//3) e and the 'down' quark (denoted by d) of charge (-1//3) e together with electrons build up ordinary matter.
