DNA features. Several DNA features has been defined. (A) Double strand or single strand in the asymmetric unit. This is useful to identify those interfaces coming from the reconstruction of the biological unit. (B) Sticky ends were defined based on the specific strands and the number of free bases at their ends. (C) Presence of flipped bases. (C) Existance of nicked DNA. (E) Existance of gapped DNA. (F) Presence of modified or non-standard DNA bases. (G) Presence of opened or unpaired bases at the DNA ends. Although not depicted here, left-handed DNA conformation was also recorded (Z-DNA).
