What's the difference between diacritic and palindrome?

Diacritic


Definition:

  • (a.) Alt. of Diacritical

Example Sentences:

  • (1) Great news for Arsenal fans, who, if the summer transfer of Mesut Özil was anything to go by, love nothing more than to pull people up on the internet for accidentally forgetting to add diacritics to people's surnames.
  • (2) Shouldn't there be an umlaut or other diacritic over a vowel?"
  • (3) This paper proposes the use of a set of symbols related to the International Phonetic Alphabet (IPA) and diacritics for the description and notation of articulatory behaviours which can be perceived visually, but which have no effect on the perceived auditory quality of phonemes produced.
  • (4) Speech and prosody analyses and content analyses of transcribers' comments yielded diacritic-level profiles of these speakers' linguistic and paralinguistic behaviors in continuous speech.
  • (5) Second, they reveal that Broca's aphasics are only sensitive to the presence of an incorrect inflection when it functions as a marker of lexical category (noun vs. verb) and not when it functions as a diacritical marker (second person singular vs. third person singular).
  • (6) The names Oesophagostomum moçambiquei and Oesophagostomum santos-diasi are corrected to O. mocambiquei and O. santosdiasi respectively, since diacritic marks are not allowed under the Code of International Zoological Nomenclature.
  • (7) In the pointed spelling, diacritical signs (pointing) are added to consonantal letters to convey vowel information.

Palindrome


Definition:

  • (n.) A word, verse, or sentence, that is the same when read backward or forward; as, madam; Hannah; or Lewd did I live, & evil I did dwel.

Example Sentences:

  • (1) Based on the previous finding that certain 30-mer single-stranded oligodeoxyribonucleotides (oligonucleotides) having particular 6-mer palindromic sequences could induce interferon-alpha and -gamma, and enhance natural killer activity, the present study was carried out to clarify the entire relationship between the activity and the sequence of 30-mer oligonucleotides.
  • (2) Structural analysis showed that they consisted of two pairs of hairpin-palindrome type plasmids, each derived from different parts of pGKL2, respectively.
  • (3) This phenomenon was observed by using wheat-germ RNA polymerase II and a series of double-stranded template polymers containing palindromic repeating motifs of 6-16 bp, with regulatory alternating purine and pyrimidine bases such as d[ATA(CG)nC].d[TAT(GC)nG], with n = 1, 3 or 6 referred to as d(GC), d(GC)3 or d(GC)6, respectively.
  • (4) The thyroid hormone-retinoic acid receptor heterodimer exhibits novel transcriptional properties in that coexpression of both receptors at low levels in Green monkey kidney (CV1) cells results in a positive transcriptional effect on promoters containing a palindromic thyroid hormone response element, but has a surprisingly negative effect on a thyroid hormone response element derived from the alpha myosin heavy chain gene.
  • (5) Many of these palindromes encode identical oligopeptides on both strands.
  • (6) Our data suggest that the sequence determinants of mutational probability at these two sites lie outside the 8 bases of the palindrome and that mutagenesis at one, but not the other, site is sensitive to perturbation of cellular calcium levels.
  • (7) Fos and Jun proteins form a tight complex which binds specifically to the AP1 recognition sequence, a palindromic DNA element also referred to as the TPA responsive element (TRE).
  • (8) Replicative form DNA of phiX174 strain ins6240, containing a 48 bp synthetic palindrome in the J-F intercistronic region, was supercoiled in vitro to mean negative superhelical densities (sigma) ranging from 0 to 0.15.
  • (9) Interestingly, each of these fragments had a perfect palindromic estrogen responsive element (ERE) (GGT-CANNNTGACC).
  • (10) One palindromic heptamer CAGNCTG is an ideal target of one DNA-binding protein engaged in chromosome packaging and in generation of banding patterns.
  • (11) Site-directed mutagenesis revealed that steric constraints and sequence requirements for NicR1-binding are located exclusively in the palindromic sequences.
  • (12) This finding strongly supports the hypothesis that Fos and Jun form a nearly symmetrical DNA-binding site that interacts with the palindromic TRE.
  • (13) In the somatic macronucleus of Tetrahymena, the rDNA is in the form of linear palindromic molecules.
  • (14) These and other data implicate a linear rather than a cruciform conformation of the oriS palindrome in the initiation of HSV replication.
  • (15) Further studies are needed to determine whether this palindrome is implicated in a feed-back loop regulating oestrogen synthesis in granulosa cells.
  • (16) We suggest that receptor recognition of the HRE is analogous to that of the helix-turn-helix DNA binding motif in that the receptor binds to DNA as a dimer with the first 'zinc finger' lying in the major groove recognizing one half of the palindromic HRE, and that protein-DNA interaction is stabilized through non-specific DNA binding and dimer interactions contributed by the second 'zinc finger'.
  • (17) After introduction of these fusions into the chromosomal DNA of mutants affected in sacB regulation, it was possible to reveal different targets for the regulatory genes sacU, sacQ and sacS: the sacU and sacQ genes act on a region located near or just upstream from the promoter, and the sacS gene, which is involved in the induction process, acts on the palindromic structure.
  • (18) This regulatory sequence is about 50 base-pairs long and is centered 125 base-pairs upstream from the transcription start site in a region containing a 16 base-pair palindromic structure.
  • (19) These palindrome-containing vectors therefore transform such strains at a very low frequency unless a DNA fragment is cloned within the polylinker at the center of the palindrome.
  • (20) Gel retention assays and DNase I footprinting with the nuclear proteins of monkey cells showed that the 5'GAGGC3' pentanucleotide repeats on either side of early palindrome domain interact with monkey nuclear protein.
