Example sentences for: intron-exon

How can you use “intron-exon” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • With the exception of the retrotransposition events discussed below, the intron-exon structure of gene models is highly conserved as well: only one case of intron gain was observed in the D. littoralis Rh2 , as has been reported previously for Rh2 in the closely related species,

  • This allows the curator to modify intron-exon boundaries base by base, split and merge genes, and export genomic or translated sequence.

  • Determination of intron-exon boundaries

  • As in the annotation of the Release 3 euchromatic sequence, the increased numbers of ESTs and cDNA sequences available for alignment to the WGS3 heterochromatic sequence resulted in significant improvements in the annotation of untranslated regions (UTRs), alternative transcripts, and intron-exon structures (see Supplementary Table 2 in additional data files).

  • The Neo 3' splice site contains a potential branch point sequence, and the sequence (CAGG) across the intron-exon boundary is optimal according to the scanning model of 3' splice site selection [ 54 55 ] . The Neo site differs from the typical 3' splice site in that it lacks a polypyrimidine tract; however, this feature is often missing from alternative splice sites [ 56 ] . Both the A of the branch point and the intron-terminal AG dinucleotide are considered invariant; therefore, one may be able to enhance the mutagenic efficiency of U3Neo vectors by altering these nucleotides.
