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.
Can you give a sentence for characteristic?
"Aggressiveness is characteristic of this species."
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.

Is 'mutations are beneficial to organisms' a true statement about mutations?
Not always. Mutations can have either beneficial, neutral, or harmful effects on organisms. Whether a mutation is beneficial or not depends on how it impacts the organism's ability to survive and reproduce in its environment.
Is cancer the result of a single mutation?
No. Usually there have to be a lot of mutations which build up.
How do mutation affect us?
Mutations can have various effects on organisms, including causing genetic disorders, changing physical traits, or even providing benefits such as resistance to diseases. In humans, mutations play a role in the development of certain cancers and inherited genetic conditions. Some mutations are harmless and can accumulate over time, leading to genetic diversity within populations.
What usually increases the appearance of a genetic disorder?
The appearance of a genetic disorder is usually increased by factors such as consanguineous (related) parents, inherited mutations from both parents, or environmental factors that trigger the expression of genetic mutations.
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.
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 does the process of carcinogenesis usually begin with?
Carcinogenesis usually begins with the accumulation of genetic mutations in a cell that lead to uncontrolled cell growth and division. These mutations can be caused by various factors such as exposure to carcinogens, radiation, or viruses.
