The motif is the repetitive supersecondary structures, an example of a motif is a beta-alpha-beta unit. The motifs are formed of the clusters of secondary structure.
On the other hand, the domains are globular and stable functional units in a protein. It may retain a three-dimensional configuration when distinguished from the rest of the protein.
Both the motifs and domains are stabilized by the hydrophobic interactions, they both are a unit of tertiary structure, and are dependent on primary composition.
The DNA double helix coils around itself simply because it is the most stable way for the atoms to interact. In other words, the DNA molecule naturally is coiled because the chemical bonds are most stable in a helix. This is the primary structure of DNA.
