More junk DNA bites the dust:-http://www.sciencedaily.com/releases/2014/03/140326141644.htm-
"Researchers studied human and mouse cells using a new technology called Cap Analysis of Gene Expression (CAGE), developed at RIKEN, to discover how 95% of all human genes are switched on and off. These "switches" -- called "promoters" and "enhancers" -- are the regions of DNA that manage gene activity. The researchers mapped the activity of 180,000 promoters and 44,000 enhancers across a wide range of human cell types and tissues and, in most cases, found they were linked with specific cell types."
