How do viruses affect the body?

A virus lodged in a cell replicates and reproduces as much as possible; with each new replication, the host cell produces more viral material than it does normal genetic material. Left unchecked, the virus will cause the death of the host cell. Viruses will also spread to nearby cells and begin the process again.

Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.

Does a virus have DNA?

Do viruses have evolution?

Viruses undergo evolution and natural selection, just like cell-based life, and most of them evolve rapidly. When two viruses infect a cell at the same time, they may swap genetic material to make new, “mixed” viruses with unique properties.

How do viruses attack computers?

Once a virus has successfully attached to a program, file, or document, the virus will lie dormant until circumstances cause the computer or device to execute its code. In order for a virus to infect your computer, you have to run the infected program, which in turn causes the virus code to be executed.
