We describe a map of 1.42 million single nucleotide polymorphisms (SNPs) distributed throughout the human genome, providing an average density on available sequence of one SNP every 1.9 kilobases. These SNPs were primarily discovered by two projects: The SNP Consortium and the analysis of clone overlaps by the International Human Genome Sequencing(More)
Single-nucleotide polymorphisms (SNPs) constitute the great majority of variations in the human genome, and as heritable variable landmarks they are useful markers for disease mapping and resolving population structure. Redundant coverage in overlaps of large-insert genomic clones, sequenced as part of the Human Genome Project, comprises a quarter of the(More)
The refined crystal structures of chicken, yeast and trypanosomal triosephosphate isomerase (TIM) have been compared. TIM is known to exist in an "open" (unliganded) and "closed" (liganded) conformation. For chicken TIM only the refined open structure is available, whereas for yeast TIM and trypanosomal TIM refined structures of both the open and the closed(More)
Reciprocal interordinal crosses were made between the sea urchins Strongylocentrotus purpuratus and Lytechinus pictus. Previous research indicated that the expression of many L. pictus genes is reduced in the hybrid embryos. The S. purpuratus gene encoding the spicule matrix protein SM50 and the L. pictus gene encoding its orthologue LSM34 were both(More)
