It belongs to a class of molecules called the nucleic acids, which are polynucleotides-that is, long chains of nucleotides. Each nucleotide consists of three components:
This structure explains two of the most important properties of the molecule. First, it can be copied or 'replicated', as each strand can act as a template for the generation of the complementary strand. Second, it can store information in the linear sequence of the nucleotides along each strand. DNA helix showing nitrogenous bases.
