RNA interference (RNAi) is a natural process that cells use to 'turn off' or silence unwanted or harmful genes.

Surprisingly, by introducing a gene for colour, they found that they had turned off the gene.
Document Actions. RNA interference (RNAi) is a naturally occurring mechanism that leads to the âsilencingâ of genes. In consequence, the respective protein is no longer synthesised. In nature, this mechanism is used for the regulation of specific genes and is also applied as a defence against viruses.NA interference (RNAi) is a naturally occurring mechanism that leads to the âsilencingâ of genes.
