  • gud job.

  • brilliant video

  • This is a great video

  • very interesting thanks

  • good work here

  • this is also called killers

  • Thumbs up if you think viruses are alive,

    Or if you like cats

  • Your voice is really sexy

  • @GhostTownLeader hahaha you think this voice is sexy? :PP its not even mine, my Bio teacher found and gave me this vid ;)

  • you wish

  • Viruses- Diseases and Conditions They Cause>Hepatitis, measles, mumps, chicken pox, meningitis, rubella, influenza, warts, colds, herpes, HIV(the virus that causes AIDS), genital warts, smallpox, Avian flu

  • that virus thingy is what i saw on jimmy nuetron!

  • our lecturer just should us this in uni last week

  • are viruses alive?

  • They look like little robots!

  • @xoFadingStarox Yea !

  • A little simplistic: virus structure can be seriously more complicated than is shown, and the expression is "bacteriophage" or "archaeophage", not just phage. SOME viruses have helical nucleopcapsids; many don't.

  • i know she said the phage infects bacteria but can it infect a persons bacteria?

  • 0:55 - this is what i think about them.

  • @ariloulaleelay sorry, 0:54

  • be carefull! those movies has subliminal message.

  • These two cyborgs are on crack

  • is this u speaking?

  • hahahaha noooooo :D

  • mhmm cool

  • viruses arent even considered alive. they are basically machines. they cannot reproduce on their own.

  • Actually Viruses are something like the living dead :P They have the characteristics of living and dead nature.

    Actually they could even be the ancestors of all the living, as they look like the link between the dead nature and the living nature. Their RNA is to something that was there long before the DNA.

  • true. you put it better. nontheless...they are not considered alive, but i cant see how you could call it dead....so the living dead is cool.

  • wikipedia says that they came from plasmids and evolved from bacteria. What RNA type are they? I know that RNA doesn't replicate with the accuracy that DNA does; could this be where they came from?

  • "I know that RNA doesn't replicate with the accuracy that DNA does; could this be where they came from?"

    Well that's actually why they mutate so fast... :D Anyway, RNA is just another nucleic acid, much more mutabile and mostly single stranded. Otherwise is the Thymine from the DNA exchanged with the Uracil.

    But RNA isn't only viral. In the end the most of our bodies functions thanks to the RNA...

    Oh and that viruses evolved from bacteria? I simply doubt that... but I'll ask someone who knows

  • for sure... My girl studies those things and she's one of the best on the faculty... very succesfull indeed, and a new species of fungi goes to her conto :D

  • it's under note 8 if you know how to write them. I was just trying to be logical. I'm new to this subject.

  • What do you mean by note 8 and if I know how to write them?

  • oh, it seems wikipedia is confused. I know that people can correct it if they have better information. I assumed you did. I was just guessing about how they came to be. I got a nice RNA lesson from the other guy, which was fine but unnecessary. I was questioning origins last night.

  • The problem is that I don't know what were you actually looking for, was it Viruses, RNA, Nucleid acids... and so on... About the language I guess It was English right? :P

    Well anyway... It doesn't matter. About the origins... Well I sincearly doubt that viruses evolved from bacteria. I oubt that heavily indeed :D, and apearently I'm repeating my self :P

    Well it's because the greater ability of the RNA to mutate and cause of the posobility of many diferent NA that could have been s. generated.

  • I never said they did. I was talking about wikipedia and its error. I don't have a text right now, and I was using my logic to rebuff it.

    What language would you like me to speak, give me 3 or 4 weeks, and I'll have a general idea.

    Anyway, "I know that RNA doesn't replicate with the accuracy that DNA does; could this be where they came from?" Yes, it is apparently, according to your reply. It was my first guess.

  • "I never said they did. I was talking about wikipedia and its error. I don't have a text right now, and I was using my logic to rebuff it."

    Yes, I've got it... I also replied as a counter for wikipedia :D

    "Yes, it is apparently, according to your reply. It was my first guess. "

    ok ;)

  • I get a little fiery sometimes. You'll have to excuse me. :(

  • "I get a little fiery sometimes."

    I didn't actually notice :P So don't vory :P

  • The fact that you can speak a billion languages is because yours come from the baltic slavic region, southern. They're all the same. If that's what you were trying to say. Or perhaps I didn't write clear enough for you. It was a simple question =P

  • No I actually didn't say anything about the language after, the point about wikipedia in english. It was because diferent languages have a diferent amount of info for the same things :P

    Otherwise I do agree on learning them is easy. Thanks to the internet and with a little bit of determination, you can get the basic idea of any language in the time of a month or so :D

  • @nomineZERO I am by no means any kind of expert on this subject, however I had always believed that viruses required a host cell to" hijack the machinery" for their own replication.

    Perhaps this is the root of the confusion.

    Also, are not prions better candidates for origins?

    they are much simpler even than virus particles?!?!

  • stupid youtube... sometimes it doesn't post my comments :S

    Short: Viruses attack only other cells which have a core (blood cells don't have so they are safe from viruses :P)

    There are so called viroids which also attack viruses.

    Oh and about the origins. I doubt I've really connected viruses with origins, maybe I've only mentioned RNA.

    About origins you can turn at liposomes. Fatty acids bound together with some amino acids forming the first NA in the core. Check abiogenesis

  • @nomineZERO Thank you for information, As I say, this is not my subject, although I hope to gain a working knowledge by browsing the more intelligent sources in time.

    It occurs to me that this is when life discovered the golden ratio.

    it began as Art :)

    in a way it gives meaning to observer as geometry here also.

    it is just fascinating and mind boggling.

    it got all my stars anyway.

  • @nomineZERO

    Viroids are just single stranded RNA without the protein coat. Viroids have only been found to infect plants like tomatoes and potatoes

  • @CuppaS00p Only plants like tomatoes and potatoes? Well I guess you're a bit wrong with that. Yeah, I know about them infecting plants, but. you can find them on viruses also, which is the interesting part.

    I admit I havent looked them up since a long time, but I still remember that first note I got about viroids was about them infecting some other viruses. Was pretty interesting to me, considering how that would work out... But... Life's full of mistery ^^

  • Maybe it sounds a bit confusing, but it's because I've made it short... Youtube didn't show my first comment, it's also the reason why I'm not as much active on youtube as I used to be... :S

  • Even if prions don't have genetic material, these certainly are a very interesting subject.

  • Viruses require a host cell to replicate, and they are unable to create their own energy. Therefore, viruses are nonliving.

  • Good video. This helped me because I'm studying virology in school right now.

  • thnx. if u need anything else just let me know :)

  • Your welcome, and thank you!

    Do you have any information on the B19 human pectovirus?
