Question

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

Explanation:

RNA nucleotides contain ribose sugar, a phosphate group, and one of four nitrogenous bases: adenine, guanine, cytosine, uracil. DNA uses deoxyribose and thymine instead of ribose and uracil.

Answer:

ribose + phosphate group + uracil
