What's the difference between hyphen and tilde?

Hyphen


Definition:

  • (n.) A mark or short dash, thus [-], placed at the end of a line which terminates with a syllable of a word, the remainder of which is carried to the next line; or between the parts of many a compound word; as in fine-leaved, clear-headed. It is also sometimes used to separate the syllables of words.
  • (v. t.) To connect with, or separate by, a hyphen, as two words or the parts of a word.

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) The H2B protein coding region of HHC289 is flanked at the 3' end by a 1798-nt nontranslated trailer that contains a region of hyphenated dyad symmetry and a poly(A) addition sequence, followed by a poly(A) tail.
  • (4) Her relations address letters to our children using an invented hyphenated surname.
  • (5) It was possible to classify the patients into three groups with focal, hyphenated and linear attachment, respectively.
  • (6) Between these extremes were cases in which hyphenations along a locus of linear attachment allowed additional communications between the ventricular compartments.
  • (7) Features of the sequence involved in recognition by the T7 RNA polymerase are discussed and include the following region of hyphenated 2-fold symmetry (boxed regions are related through a 2-fold axis of symmetry at the center of the sequence shown).
  • (8) Size, ejection and displacement indexes of the functional right ventricle measured from the angiograms suggested that the severity of the malformation increased from focal attachment through hyphenated to linear attachment.
  • (9) Its vague and fluid nature allowed space for a range of options, hyphens and elisions.
  • (10) There has been rather a lot of talk recently of hard work: the mythical individuals who are thus wired – from politicians to Hollywood stars , households of folks so hard-working they sometimes have to drop the hyphen for efficiency .
  • (11) This binding region of the beta-actin enhancer contained a hyphenated dyad symmetry and an enhancer core-like sequence.
  • (12) She is clearly not an activist of the old school.” One way to understand Watson’s very 21st-century celebrity activism is to see her as a multi-hyphenate entrepreneur in the vein of Beyoncé and Gwyneth Paltrow .
  • (13) The Sunday crossword puzzle had the following cue for 4 down: "Places for day-care" (spelled, with the purist's uncertainty, with a hyphen).

  • (15) The ends of the region of homology between pIM13 and pE194 were associated with hyphenated dyad symmetries.
  • (16) Footprints containing hyphenated palindrome sequences, found in the promoter regions of both genes, suggest the possible involvement of other classes of transcription factor.
  • (17) In the sequence alignments, identity between residues is indicated by a hyphen (-).
  • (18) The gene contains sequences that strongly resemble those found in E. coli promoters, an E. coli type of ribosomal binding site, and a hyphenated dyad sequence at the 3' end of the gene which resembles the rho-independent terminators found in some E. coli genes.

Tilde


Definition:

  • (n.) The accentual mark placed over n, and sometimes over l, in Spanish words [thus, –, /], indicating that, in pronunciation, the sound of the following vowel is to be preceded by that of the initial, or consonantal, y.

Example Sentences:

  • (1) Variance components were estimated by the tilde-hat approximation to REML.
