| The commentary is coming. It'll say something like this: Scene 1: The N1H1 virus. Scene 2: (48 seconds): Cells are tiny - and you can only see them under a microscope, but viruses are exceedingly small. They are so teeny tiny that you can only see them using an electron microscope. If a human cell was the size of an elephant, a virus would be the size of a fly. Scene 3 (53 seconds) the virus lands on a cell. Did I say that the virus is small? Scene 4: (59 seconds): the virus starts to enter the cell by burrowing into the cell wall. Scene 5: (1:03): the virus sinks down Scene 6: (1:06): as the virus enters into the cell, the cell wall closes around the virus, forming a bubble around it. Scene 7: (1:15): the hole closes up, and the virus is completed encased in a bubble from the cell wall. Scene 8: (1:23): the virus now floats down into the cell, but kind of splits open, releasing the RNA inside. The bubble that has formed around the cell kind of encases the wall of the virus, but the RNA isn't encased in it. Scene 9: (1:30) a close-up of the RNA. Its similar to DNA except its spelt differently. Scene 10: (1:38): here's the nucleus of the cell with chromosomes, which are made up of DNA. They look hairy. The wee hairs are actually strands of DNA. Kind of. The RNA that you can see floating towards the cell are very small. Scene 11: (1:53): the RNA enters the nucleus. There it starts using the DNA of the human cell and starts to replicate itself. Scene 12: (1:59): If someone ... |
