En resumen, los nucleótidos se unen para formar ácidos nucleicos a través de la formación de enlaces fosfodiesteros entre el grupo fosfato de un nucleótido y el grupo hidroxilo en el azúcar del siguiente nucleótido. En el ADN, los nucleótidos se unen formando una doble hélice, en la que los enlaces fosfodiéster se establecen entre los azúcares y los grupos fosfato de los nucleótidos adyacentes en cada cadena. The busy city was bustling with life, full of lush gardens, ornate houses, and markets loaded with exotic goods from India, Arabia, and Egypt. Los nucleótidos se forman por la unión mediante un enlace éster, de una molécula de ácido fosfórico y un nucleósido, por el grupo hidroxilo del quinto carbono (carbono 5') de la pentosa. Enjoy exploring trails of the city carved into rock by the Nabataeans. It is visited by tourists from all over the world. La unión se realiza mediante un enlace N-glucosídico entre el átomo de carbono carbonílico de la pentosa (carbono 1') y uno de los átomos de nitrógeno de la base nitrogenada, el de la posición 1 si ésta es pirimídica o el de la posición 9 si ésta es púrica.
