Olá!!! Bom vamos lá!


O nucleotídeo é constituído de um açúcar,um grupo fosfato e uma base nitrogenada. Nesse caso estamos falando de subunidade então podemos dizer que estamos falando do RNA ou DNA, logo, teremos a desoxirribose como açúcar.


Depois teremos um grupo fosfato e assim as bases nitrogenadas ( Guanina, Timina/Uracila, Citosina, Adenina) Sendo que C combina com G e A combina com T/U , vamos usar a base T quando for DNA, e quando for RNA vamos usar U. Por isso a resposta correta é a letra B!


Espero ter ajudado em algo!
