Which of the following could be a nucleotide of rna?
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".
