WebFire and Mello tested this hypothesis by injecting double-stranded RNA molecules containing the genetic codes for several other worm proteins. In every experiment, injection of double-stranded RNA carrying a genetic code led to silencing of the gene containing that particular code. The protein encoded by that gene was no longer formed. 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. The duplex unwinds, and the RNA is …

Hence, an experiment was carried out with different dosages of HEC, namely, 0.1, 0.3, 0.5, and 0.7 g. It was found that the ratio of HEC coating onto PU improved gradually with increasing dosage of HEC, as shown in Figure S1a–c. 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.

WebIn their initial experiment, Fire and Mello injected dsRNA copies of the unc-22 gene into C. elegans embryos and watched as the embryos grew into adults that twitched and had muscle defects. This result was exciting because uno-22 was known to encode a muscle protein and null mutants of unc-22 displayed the same twitching and muscle defects.
