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 the nitrogen - containing bases adenine (A), guanine (G), cytosine (C), or uracil (U). Thymine (T) is found in DNA nucleotides with deoxyribose sugar. So an RNA nucleotide has ribose, phosphate, and uracil.

Answer:

ribose + phosphate group + uracil
