(CNN)Mourners held a heavenly birthday memorial Sunday for Victoria Martens, the 10-year-old New Mexico girl who Albuquerque police say was raped by her mother's boyfriend and then killed while her mother watched.
RNA interference (RNAi) is a natural process that cells use to 'turn off' or silence unwanted or harmful genes. The initial discovery of this phenomenon was in 1991, by scientists trying to deepen the colour of petunias. Surprisingly, by introducing a gene for colour, they found that they had turned off the gene.

Deliver the dsRNA molecule to the target cell in the target organ. 2  If the level of mRNA and the protein in the cell both decrease by at least 70%, it is likely that a successful gene silencing molecule has been developed. 3  However, delivery to the target cells and organs can be difficult.
