WebNational Center for Biotechnology Information WebMar 23, 2004 · Introns are flanked by a partially conserved coding sequence that forms the immediate exon junction sequence following intron removal from pre-mRNA. Phylogenetic evidence indicates that these sequences have been targeted by numerous intron insertions during evolution, but little is known about this process.
WebMay 31, 2012 · We found that exons in low GC content regions are flanked by introns with markedly lower GC content, whereas exons located in high GC content regions have roughly the same GC content as do their flanking introns.
