Structure of nucleic acids:

A nucleotide consists of:
1. A nitrogenous base (purine or pyrimidine)
2. A pentose sugar (ribose in RNA, deoxyribose in DNA)
3. A phosphate group

Linkage between nucleotides:

Two nucleotides are connected by a phosphodiester bond — formed between:
- The 3'-OH of one nucleotide's sugar
- The 5'-phosphate of the next nucleotide

This creates the sugar-phosphate backbone of DNA and RNA.

Other linkages:
- Glycosidic linkage: connects base to sugar within a nucleoti
