@woodwhips There are no pentagons or pentagrams on the rhinovirus. It is an icosahedral structure, 20 identical equilateral triangles.
I think however you're refering to the diagram at 0.35, which is not the rhinovirus, however the pentagrams and pentagons are receptors, which are used to gain entry to a cell by binding to a receptor on the cell (kind of a lock and key mechanism)
There wasn't really a clear example in this clip, what I was referring to are the 5 sided stars and pentagons all over the Rhinovirus. I can't add a link into the comment for a picture, but if you search Rhinovirus on google images surely you will see what I mean.
@woodwhips From what I can see on google images, yes these are receptors, which bind to ICAM-1 (intra cellular adhesion molecule 1) which is found on the host cell membrane. Which are the cells in the upper (and there is increasing evidence to suggest lower) airway.
Why do we have these host cells? How did this virus come to be? Am I correct that viruses are not alive(they don't metabolize)? So what use would there be for this little pack of DNA or RNA floating around that only serves to modify our genes and makes us feel like crap=P? Do these host cells serve any other purpose?
@woodwhips These host cells are part of the epithelial tissue, which lines the airways. Their purpose is not anything to do with these (or any virus). Viruses evolved to infect these cells.
Yes you are correct, viruses aren't alive (although they do evolve). Do can't metabolise.
These little packs of DNA like all organisms are trying to survive. However we have taken advatage of them, we use them to study gene expression, they are vectors in recombinant DNA technology
There are many factors to be thought for this (e.g. the virus in question, the infected persons immune system, has treatment been recieved etc.) However for the common cold (rhinovirus), it's average "life" span is one to two weeks, as far as I know.
Do you mean when the when the virus particle infects a cell, can that same particle go on to infect more cells?
If so the answer is no, the viral particle has injected its genome into the host for replication, and as such cannot contiue infecting cells. However the genome replicates and takes over the cells machinery to create more protein coats, which combine to create new viral particles which then escape to infect new cells. And the cycle continues....
hi
why exactly does Rhinovirus have pentagons and pentagrams on it? what made this happen?

So those are the receptors?

@woodwhips also there is research currently going on to use viruses in gene therapy (adenovirus I believe is one of the viruses being used)

Is the diagram of the rhinovirus on 0:34 or on 0:42 ?
Saweet33 1 year ago
0:42 rhinoviri are non enveloped.
