English:
RNA and DNA are polymers made up of long chains of nucleotides . A nucleotide is made up of a sugar molecule (ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).
Spanish:
El ARN y el ADN son polímeros formados por largas cadenas de nucleótidos. Un nucleótido está formado por una molécula de azúcar (ribosa en el ARN o desoxirribosa en el ADN) unido a un grupo fosfato y una base nitrogenada. Las bases utilizadas en el ADN son la adenina (A), citosina (C), guanina (G) y timina (T).
