Discoveries by a research team from Maine could help to settle a long-standing debate in genetics. Some genes are seemingly inseparable in nature; they form a haplotype-a set of genes inherited as a unit. Some researchers support the notion that mapping haplotypes may be more significant than mapping ...Researchers find promising cancer-fighting power of synthetic cell-signaling molecule
