an·ti·par·al·lel

(an'tē-par'ă-lel),
1. Denoting molecules that are parallel but have opposite directional polarity, for example, the two strands of a DNA double helix.
2. Denoting the spins of two electrons occupying the same orbital area but with different spin quantum numbers.

antiparallel

/an·ti·par·al·lel/ (-par´ah-lel) denoting molecules arranged side by side but in opposite directions.

antiparallel

(ăn′tē-păr′ə-lĕl′, ăn′tī-)
adj.
Of or relating to two adjacent molecules whose sequences of atoms or other elements run in opposite directions: antiparallel strands of DNA.

antiparallel

[-per′ələl]
Etymology: Gk, anti + parallelos, side-by-side
pertaining to molecules, such as strands of DNA, that are parallel but are oriented in opposite directions.

antiparallel

Of two structures that lie parallel to each other but that run in opposite directions. The best-known example of antiparalellism is that of the two strands in the DNA molecule.
