1) a phosphate group (same for all nucleotides)

2) a 5-carbon sugar (same for a particular type of nucleic acid - deoxyribose for DNA, ribose for RNA)

3) nucleoside (purine or pyrimidine base - varies for each nucleotide - there are 5 total - 4 for DNA (adenine, cytosine, guanine, thymine) - 4 for RNA (adenine, cytosine, guanine, uracil)
