Meanings
-
(not-comparable) (of vectors) Parallel but in opposite directions. ▸ Describing the orientations of the two strands of DNA.
Upon interaction with ss- nucleic acid (NA) targets (deoxyribooligonucleotides (ODNs) or ribooligonucleotides), they form very stable anti-parallel and parallel duplexes [3 ], and the melting temperatures of the antiparallel duplexes are 10 to 15°C higher than those of the parallel duplexes.

- (not-comparable) (of vectors) Parallel but in opposite directions. ▸ Describing two beta strands comprising a protein's secondary structure that are aligned and hydrogen bonded but where the vectors describing the amino- and carboxy-terminal ends of each strand are oriented 180° relative to one another.
