Answer:

Like DNA, RNA polymers are make up of chains of nucleotides *. These nucleotides have three parts: 1) a five carbon ribose sugar, 2) a phosphate molecule and 3) one of four nitrogenous bases: adenine, guanine, cytosine or uracil.

Hello. This question is incomplete. The complete question would be:

"Which of the following could be a nucleotide of RNA?

deoxyribose + phosphate group + thymine

deoxyribose + phosphate group + uracil

ribose + phosphate group + thymine

ribose + phosphate group + uracil"

Answer:

ribose + phosphate group + uracil

Explanation:

The nucleotide is a group formed by the association of 3 molecules - a nitrogen base, a phosphate group and a pentose glycide. Thus, we can have variations within these ligands, such as: in DNA we have the presence of pentose deoxyribose, while in RNA we have the presence of pentose ribose. In addition, DNA nucleotides are composed of the nitrogenous bases Adenine, Guanine, Cytosine and Thymine; whereas RNA nucleotides are composed of the nitrogenous bases Adenine, Guanine, Cytosine and Uracilla.

From this we can conclude that the correct answer to your question is "ribose + phosphate group + uracil".
