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.

What is the most likely effect of an error during DNA translation?
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.
When a change in the DNA of an organism which affects the gametes and can be passed down to offspring?
Genetic mutations help an organism adapt to the environment they live in. So hypothetically yes, but some mutations can create infertile off-springs which in-turn stops the mutation from being passed down. It depends mostly on the change in the DNA and weather or not the organism will continue to pass on the trait.
At which point in the eukaryotic cell cycle can a DNA mutation occur?
Synthesis. The DNA replication process can contain copying errors that may not be corrected. Most are neutral, some are deleterious and some may be beneficial mutations.
How can and organism produced by asexual reproduction be unique and different from its parent?
A organism can be unique and different from its parent when mutation occurs during DNA replication.
Are errors in DNA replication always bad?
No. The errors in copying dna gives rise to mutations within an organism, which is the key driver of evolution. The mutations which benefit the organism in surviving its environment make it more likely to reproduce, thus spreading it through the population. Mutations that arent beneficial are by the same process less likely to be spread. However sexual selection can override this general rule. As in the case of the peacock and its amazing tail. Although this tail is technically a hinderance to the peacocks everyday life, peahens have, by selecting males with the best tails, effectively designed the tail over many generations.

What genetic material are called mutations?
Sudden genetic change in the DNA of an organism called mutations.
What is a sudden permanent random change in an organism's DNA?
mutations
What is the same between mutation and adaptation?
Mutations are changes in the DNA of an organism. If these mutations help an organism survive in its environment, it would be considered an adaption.
Explain how a species can change over time?
Through mutations in DNA. If a mutation is beneficial and helps the organism survive it is passed on to the next generation which leads to the evolution of a species causing it to change.
Are mutations in the DNA sequence gene transient changes?
Successful mutations will persist. Mutations usually occur during replication. Some mutations will flourish depending on environmental factors.
What are the occasional mistakes in copying DNA called and why are they significant for evolutionary change?
Mutations. They, when beneficial, provide variations of organisms genomes for natural selection. Beneficial mutations may confer a slight reproductive advantage to the organism so that genes " promoted " into the next generation change the allele frequency of the population causing evolution.
How do mutations occur in an organism?
In the base sequence of the DNA part of the DNA changes which causes a change in the whole DNA which is called a mutation.
DNA mutations can lead to genetic disorders diseases or even the death of an organism Which of the following factors is most likely to cause a mutation in DNA?
DNA mutations can lead to genetic disorders, diseases, or even the death of an organism. Which of the following factors is most likely to cause a mutation in DNA?
How can a mutation in DNA base sequence cause a change in a trait?
Some mutations produce new traits that can help an organism survive.
How can a mutation in DNA base sequence causes a change in trait?
Some mutations produce new traits that can help an organism survive.
How can a mutation a DNA base sequence cause a change in a trait?
Some mutations produce new traits that can help an organism survive.
