title: Unusual class of Alu sequences containing a potential Z-DNA segment.
abstract: A potential Z-DNA sequence, (dA-dC)9, has been found to replace the customary A-rich region in the middle of an Alu family member in the African green monkey genome. This Alu, bounded by imperfect direct repeats, also contains an unusual 3' end and may be a member of a large subfamily of such sequences.
