What's the difference between motif and motivo?

Motif


Definition:

  • (n.) Motive.

Example Sentences:

  • (1) This receptor and a growing family of related cytokine receptors share homologous extracellular features, including a well-conserved WSXWS motif.
  • (2) We have generated a series of mutants in the two copies of this motif present in human immunodeficiency virus type 1.
  • (3) An additional 14 leader peptides in this collection (all of those that contain an arginine at -10) conform to this motif.
  • (4) In addition, region III has some structural features similar to a conserved motif found in complement receptor 1, the human C3b receptor.
  • (5) A new alternative splice site was incidently found 81 nucleotide downstream of motif II in both normal and truncated 4.1 mRNA.
  • (6) The same RNA-protein motif is used, through iron-dependent degradation of transferrin receptor mRNA, to decrease synthesis of the receptor and cellular iron uptake.
  • (7) Comparison of the human and mouse repeats revealed a highly conserved Glu-Asp core in each unit, implicating the functional significance of this motif.
  • (8) The three-dimensional solution structure of a zinc finger nucleic acid binding motif has been determined by nuclear magnetic resonance (NMR) spectroscopy.
  • (9) Sequence comparison programs suggested the presence of domains related to the RNA recognition motif found in other RNA-binding proteins, and deletion analysis revealed that the carboxyl-terminal 195 amino acids of the recombinant PTB was sufficient for specific binding to pre-mRNAs.
  • (10) Since similar loop conformations form similar "words", the structural sequence facilitates the search for common structural motifs in a family of loops.
  • (11) A new repetitive DNA region was identified in the non-transcribed spacer of human rDNA, namely a long (4.6 kb) sequence motif (Xbal element) was present in two copies.
  • (12) X-ray analysis of these crystals will permit direct visualization of the specific structural motifs and chemical features that underlie phospholipase neurotoxicity.
  • (13) Information about the three-dimensional structure or function of a newly determined protein sequence can be obtained if the protein is found to contain a characterized motif or pattern of residues.
  • (14) For PPD-specific TCCs, a possible biased usage of V beta 8, as well as possible preferential usage of a CDR3 motif, were found.
  • (15) 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.
  • (16) A sequence between residues 302 and 320 homologous to a metal-binding "finger" motif is therefore not required for origin-specific binding.
  • (17) In this report, we examined the functional significance of these six motifs for the UL9 protein through the introduction of site-specific mutations resulting in single amino acid substitutions of the most highly conserved residues within each motif.
  • (18) These sequences have a number of similar motifs at, or immediately following, the end of the coding regions, motifs that may be involved in their S mRNA transcription termination processes.
  • (19) The TV campaign, created by ad agency Leo Burnett, uses imagery and motifs more closely associated with Christmas than summer.
  • (20) Interestingly, the helical motif prefers to assemble parallel to the wall, whereas the beta-barrel, predominantly assembles with its principal axis perpendicular to the wall.

Motivo


Definition:

  • (n.) See Motive, n., 3, 4.

Example Sentences:

  • (1) Y aunque los motivos no están en blanco y negro, un análisis detallado sugiere que la falta de actividad física podría ser el principal factor contribuyente.
  • (2) A nivel nacional, “es probable que la mayoría de la gente haya sentido los cambios en los precios, pero no están conscientes de los motivos,” agrega García.
