How viruses evolve, and in some cases, become deadly

Researchers have demonstrated how a new virus evolves, shedding light on how easy it can be for diseases to gain dangerous mutations.

The way viruses reproduce in their host cells makes them particularly susceptible to the genetic changes that help drive evolution. 27 jan 2012 researchers have demonstrated how a new virus Just like cellular organisms: as they reproduce, their genetic material (DNA or RNA) mutates, and mutations that make the virus perform better tend to spread in the virus population. Because viruses are so minimalistic, they The scientists sed for the first time the virus called "Lambda" evolved to fd a new way to attack host cells, an novation that took four mutations to acplish.
