释义

Definition of oligonucleotide in English:

oligonucleotide

noun ˌɒlɪɡə(ʊ)ˈnjuːklɪətʌɪdˌäləɡōˈn(y)o͞oklēətīd
Biochemistry
  • A polynucleotide whose molecules contain a relatively small number of nucleotides.

    〔生化〕低(聚)核苷酸,寡核苷酸

    Example sentencesExamples
    • Creation and purification of the double-labeled oligonucleotide is synthetically demanding.
    • The purity of the double-stranded oligonucleotides was confirmed by polyacrylamide gel electrophoresis.
    • Probes are typically fairly short sequences of DNA nucleotides, called oligonucleotides, made synthetically.
    • Intermolecular tetrameric complexes are usually only formed by short oligonucleotides that contain single tracts of contiguous guanines.
    • The latter is conjugated to primer oligonucleotides that are pre-annealed to a complementary circular oligonucleotide.
    • On single-stranded oligonucleotides, all the guanines are oxidized to the same extent.
    • In apoptosis, DNA is degraded into oligonucleotides with a few hundreds of basepairs that subsequently diffuse out of the nucleus.
    • This was followed minutes later by the injection of the oligonucleotide complementary to the DNA strand immobilized on sphere S2.
    • The unzipping direction (order of nucleotides unzipped) was controlled by the selection of oligonucleotides.
    • The unmodified polynucleotides may be DNA, RNA or synthesized oligonucleotides.
    • This problem would be enhanced using arrays composed of long oligonucleotides since only RNAs whose protected regions overlap with the oligo sequence would be identified.
    • We have been examining the potential use of oligonucleotides to direct nucleotide exchanges in episomal and chromosomal genes.
    • The peptides can be linked to a large protein or an oligonucleotide, which may then be carried through the cell membrane.
    • The proper orientation and the sequence of the cloned oligonucleotides were checked by nucleotide sequencing.
    • For single bulges in RNA oligonucleotides, the conformation usually depends on the nature of the flanking base pairs.
    • One important application is gene therapy, where it is necessary to deliver a gene or a synthetic oligonucleotide into the cell.
    • In vitro studies on novel DNA structures have mainly involved synthetic oligonucleotides based on naturally occurring sequences.
    • Liposomal formulations of genetic drugs such as antisense oligonucleotides and plasmid DNA are difficult to achieve.
    • These studies demonstrate that pre-existing cytosine methylation on oligonucleotides…
    • The latter is generally restricted to oligonucleotides but offers higher specificity.
