Genetics: Mutations

What is a genetic mutation?

• A genetic mutation is a permanent alteration in the DNA sequence that makes up a gene.

• A genetic mutation is a reversible alteration in the DNA sequence that makes up a gene.

• A genetic mutation is a change in the RNA sequence that makes up a gene.

• A genetic mutation is a temporary alteration in the DNA sequence that makes up a gene.

What are the different types of genetic mutations?

• Insertion mutations

• Deletion mutations

• Substitution mutations

• Point mutations, frameshift mutations, chromosomal mutations, silent mutations

How do genetic mutations occur?

• Genetic mutations occur due to eating spicy food

• Genetic mutations occur due to changes in the DNA sequence.

• Genetic mutations occur due to exposure to sunlight

• Genetic mutations occur due to lack of exercise

What are the effects of genetic mutations?

• Genetic mutations can have various effects such as causing genetic disorders, diseases, or beneficial traits.

• Genetic mutations have no impact on an organism

• Genetic mutations only cause diseases

• Genetic mutations always result in beneficial traits

Can genetic mutations be inherited?

• Yes

• Rarely

• Sometimes

• No

Give an example of a genetic disorder caused by a mutation.

• Cystic Fibrosis

• Sickle Cell Anemia

• Hemophilia

• Down Syndrome

How are genetic mutations diagnosed?

• Genetic mutations are diagnosed through physical examination

• Genetic mutations are diagnosed through genetic testing, DNA sequencing, and analyzing family history.

• Genetic mutations are diagnosed through blood pressure monitoring

• Genetic mutations are diagnosed through X-ray imaging

What are some factors that can increase the likelihood of genetic mutations?

• Excessive sunlight exposure

• Exposure to mutagens, errors in DNA replication, inherited genetic conditions

• Consuming genetically modified foods

• Regular exercise

How can genetic mutations be treated or managed?

• Gene therapy, medication, surgery, and lifestyle changes

• Mindfulness practices

• Physical therapy

• Herbal remedies

What is the role of genetic mutations in evolution?

• Genetic mutations always lead to beneficial traits

• Genetic mutations cause extinction of species

• Genetic mutations introduce new genetic variations into populations, which can be acted upon by natural selection to drive evolutionary change.

• Genetic mutations have no impact on evolution
