Genethon, Massachusetts Institute of Technology/ Whitehead Center for Genome Research other research news
Genethon reported in Nature that it has completed its mapping project of the human genome. The map is composed of microsatellites, markers of short, tandem repeats of two or three nucleotides, which are easier to use and more informative than earlier markers because they reduce the area scientists need to search for the basis of multigenic disorders. This map consists of 5,264 markers, about one marker every 700,000 base pairs.
Similarly, Whitehead researchers reported in Nature the completion of their five-year mouse genome mapping project. The map contains 7,377 genetic markers, consisting of 6,580 simple sequence length polymorphisms integrated with 797 restriction fragment length polymorphisms in mouse genes. There is about one marker for every 400,000 nucleotide bases. ...
