how does it stimulate an immune response?
It prevent the self-propagation of transposons and induces gene silencing in plants.
RNA interference
prevent the self-propagation of transposons
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 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. does rna cause viral infections? Yes, HIV, HPV, hepatitis A, hepatitis B etc

RNA interference [SEP] Immunity
RNA interference is a vital part of the immune response to viruses and other foreign genetic material, especially in plants where it may also prevent the self-propagation of transposons. Plants such as "Arabidopsis thaliana" express multiple dicer homologs that are specialized to react differently when the plant is exposed to different viruses. Even before the RNAi pathway was fully understood, it was known that induced gene silencing in plants could spread throughout the plant in a systemic effect and could be transferred from stock to scion plants via grafting. This phenomenon has since been recognized as a feature of the plant adaptive immune system and allows the entire plant to respond to a virus after an initial localized encounter.
