The diagram shows a type of chromosomal mutation.
What type of mutation is shown?
Deletion
Insertion
Duplication
Translocation
Two mutations of a genetic sequence are shown.
Part A. Which mutation would have the MOST significant impact on the gene product?
Mutation 1
Mutation 2
Which of these shows an example of an insertion mutation?
Which of these shows an example of a deletion mutation?
Hint: there are 2 correct answers
Which of these shows an example of an inversion mutation?
Which statements explain how a mutation in a somatic cell is different from a mutation that occurs in gametes?
Somatic cell mutations occur in cells that give rise to gametes.
Gamete mutations occur in cells that result in apoptosis.
Somatic cell mutations are maintained in the gene pool.
Gamete mutations are expelled from the gene pool.
Somatic cell mutations are generally not passed to offspring.
Gamete mutations are usually passed to offspring.
Somatic cell mutations will not be expressed by the individual that contains the mutation.
Gamete mutations will be expressed by the individual.
Match the following
Deletion
Inversion
Duplication
Insertion
Translocation
An illustration of how a particular DNA mutation will most affect the polypeptide produced is shown.
What type of mutation is illustrated?
Insertion
Translocation
Substitution
Deletion
When a new mutation occurs in a somatic cell of a sexually reproducing organism, what percentage of the individual's offspring are likely to inherit the mutation?
100%
75%
25%
0%
The model shows a mutation to a partial sequence of bases in a gene.
Which type of mutation does the model demonstrate?
Deletion
Insertion
Substitution
Translocation
Exposure to the building material asbestos has been linked to certain types of cancers. Asbestos causes mutations in the p53 gene, which controls tumor suppression.
Which statement best explains why people with cancer due to asbestos exposure do not pass the mutation on to their offspring?
The mutation occurred in gametic cells.
The mutation occurred in somatic cells.
The mutation is recessive.
The mutation is sex-linked.
A mutation in which types of cells would only affect the organism nd not future generations?
Egg cell and liver cell
Sperm cell and egg cell
Nerve cell and brain cell
Sperm cell and lung cell
A certain mutation in the gene for hemoglobin results in the red blood cells becoming sticky, rigid, and irregularly shaped. These irregularly shaped red blood cells block the flow of blood throughout the body. A single base mutation is responsible for these irregularly shaped blood cells.
Which of these mutations most likely results in the mutated hemoglobin gene?
Insertion
Deletion
Duplication
Substitution
Different types of mutations can occur in DNA. The diagram represents a type of mutation.
Which statement describes the mutation in the diagram?
A silent mutation results in the insertion of a different amino acid.
A substitution occurs with the adenine base.
A deletion of a cytosine base occurs.
A base is inserted into one strand of the DNA.
Which of these is the direct result of an error in the transcription of a DNA nucleotide?
The nuclear membrane is ruptured.
Amino acids do not bond to tRNA.
A codon sequence is incorrect.
Transportation of mRNA does not occur.
