Exon-intron junction sequences

Postby summer » Wed May 11, 2005 6:47 am

I wonder do the genes have the same exon-intron junction sequences or do they have different junction sequences? I was told that all genes have this general junction sequences of the exon-intron-exon:

5'---exon---A/CG-><-GUPuAGU----intron-----Py12NPyAG-><-G---exon---3'
The arrows indicate the borders/junctions of exons and intron. When this intron is cut out and the exons are united we would have this exon-exon sequence:

5'---exon---A/CG-><-G---exon---3'.



How can i check which sequences are exon-intron junctions and which are not?



Thanks.
