Parallel nucleic acid double strand is possible but it is not as stable as the antiparallel form ( Szabat and Kierzek, 2024 ). This is because the nucleobases are not aligned in a way that is conducive for the Watson-Crick (WC) type base pairing. In parallel conformation, the bases can form Hoogsteen (HS) and reverse …
