Health Term III : The Existence of Virus in Universe


Powered by FeedBurner

Refer to my previous posts most of diseases caused by virus. Then today I try to write about what virus is. Its existence in this universe. So we all do understand what the meaning of virus itself and its reference due to diseases. Here we go what definition of virus is ( but this is only a simple view, please if anyone eager to enrich this part, kindly sending me email ). Hope it will be useful for all of us.

" Virus is the smallest type of germs that cause disease which has sized approximately 
0.5 to 0.01 the size of the smallest bacteria " 

The difference between virus and bacteria is in the structure and the way of breeding of virus were far more modest than bacteria.

Up to now, the presence of virus is still questionable. Whether the virus is including in living creatures or just a collection series of molecules that can reproduce itself in a state favorable for the virus itself.
The main work of virus is attacking the other organism cells, which then invasion and make it that cell to be its own place culture to do reproducing. Once the virus outside the cells, it can not be able to do it works. Virus can not hold its typical work-scheme as other living creatures do: such as metabolism processing ( processing nutrients in the body ).

Virus is a parasitic form to all living creatures in the universe as like in mammals, reptiles, birds, insects, plants, algae, even in bacteria. Most viruses are caused disease, although some are not. 


Virus Structure and Its Method of Breeding

Note: In this part, I would write the interesting subject of virus. How they formed itself as like they are maths experts in doing this. I appreciate this part, that every creatures has their own unique characteristic, then it make me so in love with all this universe which has shown us in every single creature in life.

  • A virus that consists of only 1 piece of nucleic acid core which surrounded by 1 or 2 protective layers that made from protein. 
  • This protective layer is formed by a number series of sub-unit protein arranged to be congruent symmetrical shape, such as spiral like a tube or square formed ( don't we notice this, it is like geometry isn't it ? )
  • Beyond the first layer there is again a second layer which called by virus envelope. This envelope consists of protein as well. Sometimes the envelope disappears when the virus enters the cell. 
  • Nucleic acid which contained in the nucleus of a virus called genomena. Genomena consists of a string of genes that has command codes to multiply the virus itself. 
  • Virus core was divided into 2 types; viral core may contain DNA or RNA. 


Later if  I have permission to put the image. I will enrich this article with an image. Because that's great view, a simple one image I found.
