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 consist of ribose sugar (not deoxyribose which is in DNA), a phosphate group, and one of the nitrogenous bases: adenine (A), guanine (G), cytosine (C), or uracil (U). Thymine (T) is a base found in DNA, not RNA.

Answer:

ribose + phosphate group + uracil
