What's the difference between dyad and hexachord?

Dyad


Definition:

  • (n.) Two units treated as one; a couple; a pair.
  • (n.) An element, atom, or radical having a valence or combining power of two.
  • (a.) Having a valence or combining power of two; capable of being substituted for, combined with, or replaced by, two atoms of hydrogen; as, oxygen and calcium are dyad elements. See Valence.

Example Sentences:

  • (1) The 3' end of the cell cycle regulated mRNA terminates immediately following the region of hyphenated dyad symmetry typical of most histone mRNAs, whereas the constitutively expressed mRNA has a 1798 nt non-translated trailer that contains the same region of hyphenated dyad symmetry but is polyadenylated.
  • (2) Termination of sar RNA synthesis occurs after transcription of the first and second Ts of a TTTA sequence following a region of hyphenated dyad symmetry.
  • (3) Sixty mother-toddler dyads (30 boys and 30 girls) participated as subjects.
  • (4) The reciprocal (equivalent) and nonreciprocal (excessive giving or receiving) exchange of services was measured by the frequency of exchange and perception of potential support between the dyad.
  • (5) Because current family systems theory indicates that positive individual relationships within a dyad (e.g., child-mother) should be related to an overall favorable impression of the family system, we hypothesized that these two instruments should demonstrate convergence on selected dimensions.
  • (6) The purpose of the study was to determine the effect of two interventions, Calorie Management and Socioemotional Growth Fostering, on (a) the weight of children aged 1 to 3 years with nonorganic failure to thrive and (b) the interaction behaviors of 10 mother-child dyads.
  • (7) Most of the literature on this subject has indicated, contrary to the findings reported here, that full and intense erotic transference manifestations are rarely if ever seen in this therapeutic dyad.
  • (8) (2) The peak-to-peak spacing in this distribution is significantly different from 10.3 bases in the region covering three helix turns immediately 5' of the dyad axis.
  • (9) Assertive needs produced the largest number od dyads which discriminated (p less than .05) clinical and control groups.
  • (10) However, two mutations which increased the dyad symmetry of part of the binding site yielded ligands with a higher affinity for MDBP.
  • (11) This mutation is partly located within a region of dyad symmetry.
  • (12) The purpose of this study was to compare dyadic interaction behavior of traumatically disabled and nondisabled men paired in homogeneous or mixed dyads.
  • (13) MCM1 binds to the dyad symmetry element 5'-CCTAATTAGG and related sequences, which we refer to as MCM1 control elements (MCEs).
  • (14) Data also suggest that black dyads are represented more frequently in the positive categories, and white dyads are more likely to be categorized as "apathetic" or "hostile."
  • (15) (2) Coincident disomy increased as a function of the mean number of disomic chromosomes per spore in each dyad, but this increase differed functionally from that expected if coincident disomy in the two ascospores were a simple, meiotically independent, concomitant of multiple disomy.
  • (16) Binding sites for the GAL4-positive regulatory protein have been identified upstream of six galactose-inducible genes of Saccharomyces cerevisiae on the basis of (i) protection in DNAse I footprints, (ii) loss of protection when excess GAL4-binding oligonucleotide is added and (iii) homology with a 23-bp dyad-symmetric consensus sequence.

  • (19) Maternal stimulation and co-ordinated infant signalling in AGA dyads, and infant quietness and maternal activity encouraging quietness in SGA dyads, were patterns in high-scoring subjects.
  • (20) Encouragement of open, direct communication between members of a dyad may produce favorable or unfavorable results, depending upon the situation.

Hexachord


Definition:

  • (n.) A series of six notes, with a semitone between the third and fourth, the other intervals being whole tones.
