It's because the enzyme RNA dependent RNA polymerase that synthesizes RNA does not have the activity of proof reading while DNA polymerase has this activity. Because of this absence of proof reading, wrong bases are inserted without correction and hence mutation is faster.
Yes, viruses evolve over time. They will usually mutate into a stronger virus. When viruses face something new that could stop them, they usually mutate.
Viruses grow and develop by infecting host cells and using their machinery to replicate. They can mutate and evolve over time, leading to new strains and variations.
during replication RNA-polimeraze it make a lot of erros.In this ways RNA viruses it mutate faster than DNa viruses.
If you are talking about virus as in illnesses, then it is because they are immune to antibiotics and mutate. If you are talking about computer viruses they are hard to totally eliminate as they constantly mutate
Yes, viruses can mutate to infect new species.

The time it takes a virus to mutate varies depending on the virus. However, viruses mutate frequently so it is very difficult to completely eradicate a virus.
Viruses replicate quickly and mutate frequently during their life cycle, which allows them to adapt rapidly to new environments and hosts. This high mutation rate gives viruses the ability to evolve and potentially jump to a different host species. Additionally, some viruses have broad host ranges due to their ability to bind to receptors that are conserved across different species.
true
Viruses are difficult to cure because they invade host cells to replicate, making it challenging to target them without harming the host cells. Additionally, viruses can mutate quickly, leading to the development of resistance against treatments. This complexity makes it challenging to develop a universal cure for all viruses.
true
Viruses use their host's metabolic enzymes and some viruses mutate very quickly so they can easily become resistant to drugs. Viruses are almost biologically inert until they infect a cell.
