Structure of the Molecule
Each strand of the double helix carries a sequence of bases, arranged something like letters in a four-letter alphabet.
The base pairs can be copied when hydrogen bonds break and the strands pull apart.
When DNA is copied, the sequence of base pairs is copied, so genetic information can pass unchanged from one generation to the next.
