what are the variations among organisms?
Its interference can be both systemic and heritable in plants and "C. elegans", although not in "Drosophila" or mammals.
RNA interference
The effects of RNA interference can be both systemic and heritable in plants and "C. elegans", although not in "Drosophila" or mammals.
what is rna interference? It is a biological process. what does it do? RNA molecules inhibit gene expression or translation, by neutralizing targeted mRNA molecules. what does rna stand for? Ribonucleic acid how has it evolved? UNANSWERABLE what relation does it have to medicine? It was observed that introducing sense and antisense RNA to par-1 mRNA in "Caenorhabditis elegans" caused degradation of the par-1 message. what relation does it have to cancer? It can provide a more specific approach to inhibit tumor growth by targeting cancer-related genes. how is this disease treated with rna? Chemotherapeutic agents and inhibit cell invasion and migration

RNA interference [SEP] Variation among organisms
Organisms vary in their ability to take up foreign dsRNA and use it in the RNAi pathway. The effects of RNA interference can be both systemic and heritable in plants and "C. elegans", although not in "Drosophila" or mammals. In plants, RNAi is thought to propagate by the transfer of siRNAs between cells through plasmodesmata (channels in the cell walls that enable communication and transport). Heritability comes from methylation of promoters targeted by RNAi; the new methylation pattern is copied in each new generation of the cell. A broad general distinction between plants and animals lies in the targeting of endogenously produced miRNAs; in plants, miRNAs are usually perfectly or nearly perfectly complementary to their target genes and induce direct mRNA cleavage by RISC, while animals' miRNAs tend to be more divergent in sequence and induce translational repression.
