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 how does it stimulate an immune response? It prevent the self-propagation of transposons and induces gene silencing in plants. what role does it play in insecticides? It is under development as an insecticide. what is the full form of the first viral infection that you mentioned? Human immunodeficiency viruses

HIV [SEP] Discovery
The first news story on "an exotic new disease" appeared May 18, 1981 in the gay newspaper "New York Native". AIDS was first clinically observed in 1981 in the United States. The initial cases were a cluster of injection drug users and gay men with no known cause of impaired immunity who showed symptoms of "Pneumocystis" pneumonia (PCP or PJP, the latter term recognizing that the causative agent is now called "Pneumocystis jirovecii"), a rare opportunistic infection that was known to occur in people with very compromised immune systems. Soon thereafter, additional gay men developed a previously rare skin cancer called Kaposi's sarcoma (KS).
