HOUSTON (May 3, 2007) The identification of a cluster of essential genes on mouse chromosome 11 as well as similar clusters on the chromosomes of other organisms including humans buttresses the argument that there may be rules as to how genes are structured or laid out on chromosomes, said the Baylor ...Tree rings show elevated tungsten coincides with Nevada leukemia cluster
