Inverted re- peats have the potential to adopt cruciform (meaning “cross-shaped”) structures if the normal interstrand base ... as nor- mal DNA duplexes because an unpaired segment must exist in the loop region. Cru- ciforms potentially create novel structures that can serve as distinctive recognition sites for specific...
