Stacking


Definition:

  • (p. pr. & vb. n.) of Stack
  • () a. & n. from Stack.

Example Sentences:

  • (1) Thin films (OD approximately 0.7) of glucose-embedded membranes, prepared as a control, showed virtually 100% conversion to the M state, and stacks of such thin film specimens gave very similar x-ray diffraction patterns in the bR568 and the M412 state in most experiments.

  • (5) Carcinogen-modified oligodeoxynucleotides were single-stranded, but there were often considerable stacking interactions between the pyrenyl residues and the oligonucleotide bases, indicating that electrophoresed oligomers were single-stranded but in a native, versus random coil, conformation.
  • (6) Intermolecular contacts occur in both oligomers in the minor groove: in the B form through twisted guanine-guanine hydrogen bonding, and in the Z form through base-base stacking and the water network.
  • (7) If we were to have a plebiscite before the end of the year, and you were to reverse-engineer that, it would make interesting speculation about the timing of an election.” Abetz said in January he would need to see whether a plebiscite was “above board or whether the question is stacked” before deciding to heed any result in favour of marriage equality.
