A single nucleotide difference at the 3' end of an intron causes differential splicing of two histocompatibility genes.


The murine histocompatibility class I genes, H-2 Kb and Kk, display considerable homology at their 3' ends. In fact, from exon 5 to the termination codon, only two nucleotides differ between the two genes, one at the 5' end and the other at the 3' end of intron 7. Despite this similarity, the gene products have distinctly different mol. wts as determined by… (More)
