Mutations are random. They may be beneficial, detrimental, or have no effect at all.

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.
Two causes of mutation?
Two types of mutations are Point Mutations and the other is Frameshift Mutations. Piont mutations include; deletions, insertions, and substitutions. These mutations casue a slight change in the amino acid usually resulting in a change in one amino acid. The second type, frameshift mutations involve many changes and almost always results in many changes in the codons.
Although genetic mutations may occur spontaneously in organisms the incidence of such mutations may be increased by?
Radioactive substances in the environment
What characteristic of a civilization usually provides a sound basis for advances in art and science?
A surplus of food, and organised government capable of protecting the society.
How can mutations affect protein synthesis?
it can cause cancer
Is 'mutations are beneficial to organisms' a true statement about mutations?
Usually mutations have deleterious effects to the organism, but occasionally there are beneficial mutations. Such mutations drive evolution.
Do people usually have more mutations in their cells than animals do?
Since mutations are usually caused by radiation, I would say people have more mutations. A lot of what we use everyday causes radiation. Cell phones, computers, etc.
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 do Multifactoral Disorders usually result from?
mutations in multiple genes

What kind of mutations will always be passed to offspring in the gametes or reproductive cells of organisms?
All characteristics were at some point mutations. Successful genetic mutations that are present in a parent in the homozygous form willl always be transmitted into the gametes. Whether the offspring will have the characteristic phenotypically hinges ont the genetics of both parents and which alleles are in the fertilized egg.
Is cancer the result of a single mutation?
No. Usually there have to be a lot of mutations which build up.
Why Mutations can be considered one of the raw materials of evolution because they?
are usually harmful
Has there ever been cases of mutations due to nuclear radiation?
Fruit flys and other insects. In humans the levels needed to produce inheritable mutations are usually fatal.
What if something goes wrong during mitosis?
Usually mutations or possibly death of the cell.
Mistakes during the duplicating process toxic chemicals or radiation are usually responsible for?
MUTATIONS
What can cause changes in DNA sequences?
mutations
