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.
Interference is a process of the formation of new wave with lower or higher amplitude by superimposition of two waves. It is the interaction process of two waves which are produced from either same source or same frequency. This effect is seen for all types of waves.
