WebThe Nobel Laureates in Physiology or Medicine for 2006, the American scientists Andrew Fire and Craig Mello, have discovered a fundamental mechanism of gene regulation. They have shown that double-stranded RNA molecules can silence a gene by elimination of the mRNA corresponding to that gene. This is called RNA interference (RNAi) and occurs in ... WebNov 21, 2024 · From the study using C. elegans, a unique mechanism to suppress the function of gene was discovered by Nobel physiology/medicine prize winner Andrew Z. Fire and Craig C. Mello (Fire et al. 1998) and that called RNAi. RNAi is a phenomenon in which mRNA is degraded in a sequence-specific manner by double-stranded RNA (dsRNA), … WebThe mechanism of RNA interference can be explained in the following steps: Long double-stranded RNA is diced into small fragments with the help of an enzyme called Dicer. These small fragments are known as siRNA or small interfering RNA. The siRNAs are passed through the RNA-induced silencing complex.

WebIn the Fire and Mello experiment, which led to the discovery of RNAi, it was observed that injecting embryos with dsRNA sequences representing both the sense and antisense strands of the mex-3 gene led to a near complete elimination of mex-3 transcripts in the injected embryos. WebFire and Mello repeated the experiment with three more C. elegans genes, and observed a similar effect every time; pheno-types similar to the null mutants of the respective genes were observed. Thus, the phenomenon is ‘specific’ and works for all genes. Fire and Mello injected the RNA into the worm and
