A retrovirus is a kind of virus that stores its genes as RNA, not DNA. When it gets inside a cell, it does something most living things do not: it that RNA “backwards” into DNA, and that DNA can settle into the host’s own genes. That reverse step is why it is called retro-. HIV, the virus that causes AIDS, is a retrovirus. Some viruses linked to cancer are too. The same trick that makes these viruses dangerous also makes them useful: scientists can take a retrovirus and use it like a delivery truck to carry a helpful gene into a cell. That is why the word shows up both in grim health news and in genetic engineering. Though actually, not every serious virus is a retrovirus — a cold virus is not. The “retro” is about the copying direction, not about being old-fashioned.
組成retro- (“backwards”) + virus. Named for its reverse direction of replication: RNA first, then DNA.
