Transparent, but if it was, you would see some genetic Genetic material, which might be DNA or it might be RNA. Of a bunch of little proteins put together. Proteins, these protein capsids, are just made up Much any possible way of replication probablyĭoes somehow exist in the virus world. The surface and understanding even what virusesĪre out there and all of the different ways that theyĬan essentially replicate themselves. And it's just contained insideĬalled the capsid. Stranded RNA or single or double stranded DNA. Some genetic information, some chain of nucleic acids. Viruses can come in all of these forms- is that they have They'll write these two little S's in front of it. So it can be an RNA, it couldĭouble-stranded RNA. And the genetic informationĬan come in any form. Just a bunch of genetic information inside I mean, I could- I'm kind ofīutchering the taxonomy system here, but we tend to know It's born, it grows, it's constantly changing. Or life as one of those things that you know What is life? I mean if we look at ourselves, Because they really blur theīoundary between what is an inanimate object and On some level, the most fascinating thing inĪll of biology. Right now, I can't imagine a more appropriate topic to makeĪ video on than a virus. This ability was gained by a frameshift mutation of a gene the bacterium had more than one copy of (this is known as a duplication and frameshift mutation).īut, again, in nearly all cases a frameshift mutation is quite harmful because it totally changes the protein being produced, making an entirely different protein. For example, there is a bacterium that can digest byproducts of the manufacture of nylon. For example, cystic fibrosis is caused by a frameshift mutation.Īlthough exceedingly rare, there are documented cases of a frameshift mutation being beneficial. In almost all cases, this mutation is harmful, usually causing diseases. A frameshift mutation is one common type of mutation that produces a completely new protein. However, it is possible for a single mutation to cause a completely new protein to be produced. I think it is rather unlikely that a spontaneous mutation would just so happen to produce a protein that would be identical to a protein produced by a virus. ![]()
