Upon infecting new bacteria, the viruses incidentally leave genetic material of previous bacteria in the new one [source: Marraffini]. Swapping genetic material gives bacteria the flexibility to adapt — and some do, once they sense stressful changes in the environment such as food shortages or ...

microbes,viruses, toxins and parasites that would love to invade your body. To understand the power of the immune system, all that you have to do is look at what happens to anything once it dies. That sounds gross, but it does show you something very important about your immune system. ...
Deadly outbreaks have plagued societies for centuries. But they can lead to medical breakthroughs—if we learn the right lessons from them.
These vaccines are made when the virus is weakened to such a level that it reproduces only about 20 times in the body. By comparison, 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 ...
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...
Viruses 3. What do viruses and living organisms have in common? Both use nucleic acids to store genetic information in the form of DNA or RNA Both change over time (evolve) Viruses 4. If viruses do not have their own metabolism to grow and reproduce, how do they survive? By hijacking ...
As far as the virus is concerned - and think of it like a Terminator, since it's not really alive - the purpose of replication is simple. Just survival. No longer term goals. By makin' copies of its genome and packing those copies into viruses, it is able to ...
