Nucleotide sequence homology at 12 intron–exon junctions in the chick ovalbumin gene

Abstract
A short partial sequence homology is present at all intron-exon junctions, or splice points, in the chick ovalbumin gene; it is probably a signal for a splicing enzyme. The significance of the junction sequences for splicing is discussed. No evidence was found of strong Watson-Crick base pairing between adjacent junctions.
