Most of the time, a mutation in a virus results in better ability to infect a host cell and more resistance to the host cell's defenses.

What is sequential mutation?
It's a double mutation that occurs on a colony of cells (bacteria for example) that claims to have resistance to two different antibiotics or viruses. This double mutation, however, strictly happens by first developing a mutation for the first antibiotic/virus and then has an independent mutation (nothing to do with the first mutation) for the other or second antibiotic/virus.
What effects can mutation have a virus?
They create genetic variations.
Why does a mutation in a sex cell have potential for great effect?
A mutation in a sex cell can be passed on to your offspring and to their offspring as well. Therefore, its effect is greater than that of a somatic mutation.
Is a mutation deleterious?
A deleterious mutation has a negative effect on the phenotype, and thus decreases the fitness of the organism. (A harmful mutation)
Why must pharmaceutical companies develop flu vaccines every year?
Influenza is an RNA virus. Being that it is an RNA virus it has a high rate of mutation that goes unchecked. This high rate of mutation leads to different strains of the influenza virus
What is a mutation called that has no effect on an organism?
A point mutation, in which one nitrogen base in a codon is substituted for another, may have no effect on an organism. This is true if the base substitution does not change the amino acid that the codon represents, or if the mutation occurs in a non-critical location in the protein so that the protein's structure is not changed significantly and the protein is still able to function.
What is the result of mutation during of meiosis?
The mutation may be passed on to an offspring. Depending on the mutation, it may have no effect, or it could be lethal.
What is potential impact mutation?
No one knows what effect a mutation may have. Most are not viable.
What type of mutation is likely to have the least effect on an organism?
A silent mutation has the least effect on an organism. It is when the codon is changed to the same amino acid.
How is it possible for a point mutation to have no effect on the function of gene?
If the point mutation does not change the protein to be translated in the 3-letter sequence, then it will have no effect on the gene's function.
What is an example of a good effect from a mutation?
Well a Silent Mutation does not affect anything so it isn't bad so its a good mutation.
What effect does deletion mutation have on the chain?
It will shorten the chain.
