They're inherently more complex and three-dimensional than the man-made stuff and may be better at reaching the rich harvest of disease targets uncovered by genetic mapping.

Some specialists say full genetic mapping often has limited use.

They studied the nerve cells that regulate appetite using a 'genetic fate mapping' technique and found that some cells added neurons to the appetite-regulating circuitry of the mouse brain after birth and into adulthood.

BBC: Appetite control could be rewired, say researchers

Using new genetic techniques such as molecular mapping, they have located a set of genes on one chromosome that appears to control the process in a grass species called Tripsacum.

And mapping a dna profile allows the company to sell the genetic fingerprint to well-heeled Arowana fanciers for thousands of dollars extra, like a racehorse pedigree.

After years of research and the expenditure of billions of dollars, universities, research institutions and private companies succeeded about 10 years ago in mapping the human genome, showing the long string of genetic materials that's found in all cells.
