Question

which three of the following options make up a nucleotide?
amino acid
sugar
fatty acid
base
monosaccharide
phosphate
glycerol

Explanation:

A nucleotide is composed of three parts: a sugar (either ribose in RNA or deoxyribose in DNA), a nitrogen - containing base (such as adenine, thymine, cytosine, guanine, or uracil), and a phosphate group. Amino acid is the building block of proteins. Fatty acid and glycerol are components of lipids. Monosaccharide is a simple sugar but alone is not a part of a nucleotide structure (the sugar in a nucleotide is a specific type within the monosaccharide category but the term "monosaccharide" is too general here compared to "sugar" which is more context - specific for nucleotide).

Answer:

sugar, base, phosphate
