When you get the flu, viruses turn your cells into tiny factories that help spread the disease. In this animation, NPR's Robert Krulwich and medical animator David Bolinsky explain how a flu virus can trick a single cell into making a million more viruses.

  • @EminemEsteem It's actually the nucleus, like the narrator describes. After translation some of the proteins reenter the nucleus to help export the new viral RNA, while the rest of proteins go straight through the ER and golgi system and are inserted into the cell's plasma membrane. The viruses are assembled at the plasma membrane and then bud off to go infect other cells.

  • This is WAY to oversimplified to help anyone who is actually learning about viruses in class lol

  • I saw this video in my school. xD

  • I wish documentaries would stop using sound effects in their videos. It doesn't add anything to the explanation. Other than that, good information.

  • I wish they would be a little more specific; I'm sitting here, like: "No, protein channel in phospholipid bilayer membrane. Ribosome. RNA. Golgi body." not, "peanut-y things." XD but good video anyway if you're not looking for detail. The animations are awesome.

  • 103 throat cells want justice for their brothers.

  • Talk about dumbed down.
