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 when was it discovered? 1981

HIV [SEP] Discovery
Many more cases of PJP and KS emerged, alerting U.S. Centers for Disease Control and Prevention (CDC) and a CDC task force was formed to monitor the outbreak. The earliest retrospectively described case of AIDS is believed to have been in Norway beginning in 1966. In the beginning, the CDC did not have an official name for the disease, often referring to it by way of the diseases that were associated with it, for example, lymphadenopathy, the disease after which the discoverers of HIV originally named the virus. They also used "Kaposi's Sarcoma and Opportunistic Infections", the name by which a task force had been set up in 1981.
