Explanation:

La diferencia estructural clave entre ADN y ARN es que el ARN contiene uracilo (U) como base nitrogenada, mientras que el ADN contiene timina (T). Además, el ADN es doble cadena y el ARN es generalmente simple cadena.

Answer:

RNA contains the base uracil; DNA does not contain uracil.
