Do Genes Share Identical Exon-Intron Junction Sequences?

AI Thread Summary
Genes can have varying exon-intron junction sequences, although they may share general patterns. The typical junction sequence includes specific nucleotide motifs at the borders of exons and introns. To identify which sequences are exon-intron junctions, tools like JuncDB can be utilized for analysis. This resource provides a database for examining junction sequences in different genes. Understanding these junctions is crucial for studying gene structure and function.

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.

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
