Scientists have developed powerfulmicroscopesto magnify bacteria — usually ranging from one to a handful of microns (one millionth of a meter) in length, giving us a glimpse into their inner workings and how they compare to other forms of life such as plants, animals, viruses and fungi. As ...
because viruses reproduce so quickly and so often, they can often change slightly. Sometimes, mistakes creep into their genetic instructions. These changes might alter the protein coat slightly, so one year's batch of vaccine might not be ...
There are millions of viruses thought-out the world and many of them are deadly, take the Influenza virus for instance. The Influenza strain is a constantly changing virus; they change from year to year, and as the flu virus reproduces their genetic makeup may change. Due to the genetic ...
We’ve heard a lot aboutvirusesrecently, but how do they work? Viruses cannot live for long without a host. Viruses consist of either aDNAor RNA genome ( genetic code ) and a protein coat, some also have an extra fatty envelope to protect their genetic material. They cannot reproduce wit...
Viruses have a very simple structure: an outer shell made of protein that protects the genetic material, in the form of DNA or RNA, that it uses to reproduce. They cannot reproduce on their own, so they invade the cells of living hosts and use their genetic code to make the host cell...
Worms can spread and reproduce themselves very fast and independently without using any application as a transfer mode. Viruses, however, need to infect applications and programs before they can do their work. The First Virus Created The first-ever virus created in history was the Elk Cloner, cr...
As our essay in this week’s issue explains, viruses are best thought of as packages of genetic material that exploit another organism’s metabolism in order to reproduce. They are parasites of the purest kind: they borrow everything from the host except the genetic code that makes them what...
natural viruses reproduce thousands of times. When the vaccine is made, the virus or bacteria is weakened in a laboratory to the point where it's still alive and able to reproduce but can't cause serious illness. Its presence is enough to cause the immune system to produce antibodies to fi...
