What is a mutation as described in the video?

• A form of genetic conservation

• A method of genetic replication

• A type of genetic disease

• A change in the genetic material of an organism

Which type of mutation does not affect the phenotype?

• Chromosomal mutations

• Frameshift mutations

• Neutral mutations

What is a frameshift mutation?

• A mutation that occurs in every frame of genetic data

• Insertion or deletion of a number of nucleotides not divisible by three

• A mutation that shifts only the first base of the DNA sequence

• A mutation that corrects chromosomal misalignments

What can cause mutations according to the video?

• Environmental factors and errors in DNA replication

• Inheritance from parents only

• Vaccinations

• Healthy lifestyle choices

How is sickle cell anemia related to mutations?

• It is caused by a specific mutation in the hemoglobin gene

• It is unrelated to mutations

• It is a type of mutation itself

• It prevents all mutations

What type of mutation involves adding or deleting bases from the DNA, which results in new codons (a shift in the reading of the codons)?

• point mutation

• frameshift mutation

• silent mutation

• chromosomal mutation

Match the type of mutation with its definition:

• Substitution

• when one nucleotide is switched for a different one in the DNA sequence

• Deletion

• when one nucleotide is added into the DNA sequence

• Insertion

• when one nucleotide is removed from the DNA sequence

What are considered neutral mutations?

• mutations in the DNA sequence that changes the resulting protein and harms the organism

• mutations in the DNA sequence that changes the resulting protein and benefits the organism

• mutations in the DNA sequence that produces the same protein

• all mutations are considered bad and harm the organisms

Which type of mutation results in a premature stop codon?

• Missense mutation

• Nonsense mutation

• Silent mutation

• Frameshift mutation
