i think that most of the mutated genes have more then one thing wrong with them
Mutations happen in ALL living things (and also in viruses)!!!!!!
What exactly is your question? If you want to know if A can be the cause of B and C than: Yes! These mutations can also be caused by diseases, especially viruses.
The most likely effect of an error during DNA translation is a mutation. Some mutations are beneficial, some are deadly and some are what is called "nonsense" mutations. Nonsense mutations have no benefits nor do they have any "bad" consequences.
Mutations are usually anomalies in the sequence of a particular strand of DNA. The change is the sequence can be of various kinds and their individual effects vary. Sometimes mutations occur but they are never expressed. In such cases, on the whole, the mutation has had no impact. Changes in a single nucleotide can change the reading frame for protein coding regions and can cause misreading of the genetic code. For example, nonsense mutations caused by the exchange of a nucleotide leading to a stop codon can cause truncation of a protein. On the other hand, we can have silent mutations which show no effect because the nucleotide that has been exchanged does not cause change in amino acid sequence. So this would be an example of a mutation which shows no effect.
Control genes determine the magnitude of a mutation's effect. Mutations in these parts of the genome can substantially change the way the organism is built.

Viruses
frequent mutations
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.
mutations
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.
They create genetic variations.
useful effect viruses
No. Point mutations may have no effect on the protein, however, they can also be very harmful.
Mutations arise as a result of exposure to radiation, chemicals, and viruses. Many different things might act as a mutagen. Science itself probably does not cause mutations.
Bacteria and viruses change the genotype of an organism through mutation. Mutations are heritable changes in DNA and RNA that changes the genes..
