They create genetic variations.
Mutations of Bacteria from Virus Sensitivity to Virus Resistance was created in 1943.
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.
Some mutations can be deadly, harmful, or have no effect. Correct, not all mutations are harmful. Some mutations could even have a positive effect and help the creature adapt.
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 lead to changes in its behavior, including alterations in transmissibility, virulence, and resistance to treatments or vaccines. Some mutations may enhance the virus's ability to infect hosts or evade the immune system, while others could diminish its infectivity or lead to less severe disease. In some cases, beneficial mutations can drive the emergence of new variants, impacting public health responses and control measures. Overall, the effects of mutations can significantly influence the course of viral outbreaks.
Most mutations that occur have a neutral effect, or none at all, so they would not affect evolution. Organisms with mutations that cause detrimental impact typically will not survive; therefore, they will not reproduce, and the mutation will not be passed on, so the species will not be affected overall. Beneficial mutations are typically the only mutations that will affect an organism's posterity and the evolution of its species, but good mutations are very rare. This is why most mutations have little effect on the evolution of a species.
DNA change/ mutations can be dangerous
The Melissa virus is a mass-mailing macro virus. It can effect email that is sent and infect the computer when the email is opened.
No. Point mutations may have no effect on the protein, however, they can also be very harmful.
useful effect viruses
it could alter the way the animal moves and how the body works
cannot be passed on to offspring
