They create genetic variations.
A mutant virus is a virus that has undergone genetic changes, or mutations, in its structure. These mutations can alter the virus's ability to infect cells, replicate, or evade the immune system. Mutant viruses can potentially have different characteristics or behaviors compared to the original, wild-type virus.
Mutations in a virus can alter its characteristics, such as its ability to infect host cells, replicate, or evade the immune system. Some mutations may lead to increased virulence or drug resistance, while others may make the virus less harmful or transmissible. Monitoring mutations is important for understanding how a virus evolves and developing effective treatments or vaccines.
Not always. Mutations can have either beneficial, neutral, or harmful effects on organisms. Whether a mutation is beneficial or not depends on how it impacts the organism's ability to survive and reproduce in its environment.
mutations
Many. Depending on the organism, mutations can cause things like four leaves on a clover, to polydactily or sicle cell anemia. The effects can be good, bad or neutral.
DNA change/ mutations can be dangerous
That's correct. Mutations are changes in the DNA sequence that can result from errors during DNA replication, exposure to mutagens, or other environmental factors. Mutations can have various effects, ranging from no impact to influencing an organism's traits or health.
if you mean shingles virus the answer is yes
Not all mutations are bad. Some mutations can be neutral, having no effect on an organism. And in some cases, mutations can be beneficial, providing an advantage in certain environments or circumstances. However, harmful mutations can also occur, leading to genetic disorders or other negative effects.
A single virus remains unchanged over whatever period of time its a virus (which can be many years) but mutations are common during its "reproductive" cycle ... after all, it essentially dissolves in the process, becoming a part of the host cell.
