Researchers develop fast track way to discover how cells are regulated
... the worm genome is comprised of 20,000 genes. The human
genome has over 30,000 genes. "When you look at the numbers, it becomes very clear that the old way -- studying one gene at a time -- is too slow. It becomes a problem of scale, with high throughput the only answer." Mango's team used a unique proc...
