Dna 3: mation of a simplified model of the dna molecule emphasising the the sequence of base pairs that span the helix like the rungs of a ladder the structure of dna. If the two parental dna strands did not uncoil at all as they replicated, then as the watson-crick double-helix model suggests, the two progeny double helices would revolve about.
