Smg1 nonsense mutations do not abolish nonsense-mediated mRNA decay in Drosophila melanogaster.

abstract：:Determining the patterns of DNA sequence variation in the human genome is a useful first step toward identifying the genetic basis of a common disease. A haplotype map (HapMap), aimed at describing these variation patterns across the entire genome, has been recently developed by the International HapMap Consortium. In...
