In the context of genetic material, nucleotide consists of
a. N- base, Ribose sugar, Phosphate group
b. N- base, Hexose sugar, Phosphate group
c. Nucleoside + phosphate
A nucleotide is the basic building block of nucleic acids. RNA and DNA are polymers made of long chains of nucleotides. A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.
