WebDNA replication is semi-conservative. This means that each of the two strands in double-stranded DNA acts as a template to produce two new strands. Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).
