The correct answer is: base-sugar-phosphate
Nucleotides are the building blocks of nucleic acids (DNA and RNA). A single nucleotide is composed of a phosphate molecule, a five carbon sugar (either ribose or deoxyribose) and a purine (adenine or guanine) or a pyrimidine (thymine or cytosine or uracil) nitrogenous base.
Nucleoside $=$ Base + Sugar
Nucleotide $=$ Base + Sugar + Phosphate
