Rna interference (rnai) is a mechanism of gene regulation in eukaryotes. rnai is ? initiated by ? , which leads to the of specific genes.

Double-stranded RNA-mediated interference (RNAi) is a simple and rapid method of silencing gene expression in a range of organisms. The silencing of a gene is a consequence of degradation of RNA into short RNAs that activate ribonucleases to target homologous mRNA.

RNAi is a cellular mechanism responsible for post-transcriptional gene silencing that acts on messenger RNA (mRNA).

RNA interference (RNAi) is a cellular mechanism responsible for post-transcriptional gene silencing that acts on messenger RNA (mRNA). Beyond what is necessary.

Involved in this mechanism is a double-stranded RNA molecule (dsRNA) which, when incorporated in the active form into a complex in the cytoplasm, binds to a complementary nucleotide sequence located in the target mRNA, thus causing silencing, by inhibiting translation and/or degradation of the mRNA.

With this information, we can conclude that RNA interference or RNA-mediated interference (RNAi) is a mechanism that occurs naturally in plants, animals and fungi, and can act in the defense response of these organisms against the invasion of pathogens, such as viruses.
