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:

  • Gene models were checked to ensure that they did not overlap transposable elements and that they did not have major alterations of their intron-exon structure due to the presence of unmasked data.

  • 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.

  • To determine the intron-exon structure of gene models, curators visually inspected the alignment of computational evidence types to the WGS3 heterochromatic sequences using Apollo.

  • In addition, important details of gene models will prove difficult to predict using only comparative data, as amino-acid divergence (especially insertions or deletions) can obscure intron-exon boundaries and other details of gene structure.

  • 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).
