They can certainly be either. When researching it closely scientists have found a lot of mutations which don't seem to have any influence. "Bad" mutations tends not to be functional, and often disappear pretty much by themselves one way or another.
Most mutations are either neutral or harmful. There are very little mutations that has benefits.
Yes mutations are the basis of evolution as they provide variance in the phenotype that could have evolutionary advantages
some mutations are helpful. others are harmful or neutral which means they are neither harmful nor helpful.
Sometimes they're beneficial, but more often they don't change anything or are deleterious.

Mutations that succeed [are beneficial] provide Evolution, so not at all.
Genetic mutations are not always harmful to the individual. A few may be beneficial.
Gene mutations may have positive or negative effects. Without "positive" gene mutations, a species would not be able to improve itself over time, in order to make it more it more adaptable to its environment. "Negative" gene mutations, by their very nature and definition, tend not to be able to survive in their environment.
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.
"...999/1000 are harmful or fatal and the remainder may be beneficial. (Remine, The Biotic Message, page 221."
Usually mutations have deleterious effects to the organism, but occasionally there are beneficial mutations. Such mutations drive evolution.
Mutations that succeed [are beneficial] provide Evolution, so not at all.
beneficial mutations
Well, there is no specific type of mutation that is beneficial. They can be harmful, helpful, or have no effect at all.
Genetic mutations are not always harmful to the individual. A few may be beneficial.
Mutations
Mutations are random. They may be beneficial, detrimental, or have no effect at all.
This ensures that the race as a whole retains the genetic mutations that are beneficial, and that the poor genetic mutations are gradually lessened.
Those that increase your health, your survival, your ability to have children and of course too many other benefits to name, here. Generally mutations are the key to natural selection. Beneficial mutations that occur allow an organism to survive longer, thus reproduce more, passing this mutated trait down to their offspring.
Mutations
The very first mutation observed in a sheep population was having short legs. Therefore such seeps were easily herded. Likewise, many mutations introduced in crop plants and animals are beneficial to the human race.
Yes because evolution is based off of mutations makeing them improve or gain better traits and abillitys
