Inspired by science

 I finished this pair of pieces last night, They are entitled "Prelix Supra" and "Prelix Infra". The pieces are 3" x 5" (8" x 10" framed). The letters represent the complementary amino acids found in the double helix of DNA. In this case, the string of amino acids in each composition are unpaired (although the sequences of each individual composition is complementary to the other). That's from where the first part of the title comes -- "Prelix" (before "helix"). BTW, the small "u" in the composition represents "uracil" which is found in place of thymine in RNA translation of the DNA pairs. The "supra" and "infra" part of the title simply refers to "above" and "below", respectively. That's the arrangement of this pair that I intended (i.e., one above, and one below)
