Ugljik će dijeliti elektrone s dušikom, kisikom, vodikom, i kritično, s drugim ugljikom, za izgradnju to neizmjerno složenih lanaca aminokiselina i proteina koji su građevni blokovi života.
Carbon will share those electrons with nitrogen, oxygen, hydrogen, and critically, with other carbons, to build up these immensely complex chains, the amino acids and the proteins which are the building blocks of life.
