On Monday, two American scientists, Andrew Z. Fire and Craig C. Mello won the 2006 Nobel Prize in physiology or medicine for discovering a fundamental mechanism in controlling the activity of genes.

The Nobel Assembly of Stockholm's Karolinska Institute said on Monday that the two won the prestigious award for their research into gene silencing by double-stranded RNA

In a surprising experiment, researchers found that mice passed its offspring the effect of an aberrant gene without actually passing it.

In the study published in Thursday's issue of Journal Nature, scientists produced mice with one normal and one abnormal gene, by giving the subjects white patches on tail
