During rna interference

WebRNA Interference (RNAi) is one of the most important technological breakthroughs in modern biology, allowing us to directly observe the effects of the loss of function of specific genes in mammalian systems. In the early 1990s, a number of scientists observed independently that RNA inhibited protein expression in plants and fungi (Figure 1). WebRNA interference (RNAi) is one of the pathways, collectively named RNA silencing pathways, that employ small RNAs as guides for sequence-specific silencing [reviewed in ( Ketting, 2011 )]. RNAi was discovered in C. elegans and defined as sequence-specific mRNA degradation induced by long double-stranded RNA (dsRNA) ( Fire et al., 1998 ).
