What are mutations?
Changes in cellular respiration
Changes in protein structure
Changes in environmental conditions
Changes in genetic information
What type of mutation involves changes in a single gene?
Chromosomal mutations
Gene mutations
Frameshift mutations
Point mutations
What is a point mutation?
A mutation that occurs during meiosis
A mutation that involves changes in one or a few nucleotides
A mutation that is always harmful
A mutation that affects an entire chromosome
What happens during a frameshift mutation?
The reading frame of the genetic message shifts
The mutation has no effect
The entire gene is deleted
A new gene is created
What are mutagens?
Types of chromosomes
Proteins that repair DNA
Agents that cause mutations
Normal cellular processes
What is polyploidy?
A harmful genetic disorder
A process of DNA replication
A type of point mutation
A condition with extra sets of chromosomes
In a genetics class, Henry, Lily, and Michael are learning about the three types of mutations that can occur in DNA sequences. What are these mutations?
Inversion
Translocation
Insertion, Deletion, Substitution
Duplication
What type of mutation is shown in the diagram?
substitution
insertion
deletion
no change
DNA molecule segment is : TTACGCAAG
The mutated DNA segment is TTCGCAAG. This is an example of ___ mutation.
Substitution
Deletion
Insertion
Inversion
Why are insertion and deletion (frameshift) mutations so harmful?
They change all of the codons from the mutation on down the line, which changes the amino acid sequence
They insert things that an organism doesn't need.
They often delete things that organisms need.
Insertion and deletions are not any more harmful than substitution mutations.
Which of the following would result in a frameshift mutation?
Insertions only
Substitution only
Deletion only
Insertions and Deletions
What mutation has occurred here?
T-G-A-C-C-A
T-G-A-G-C-A
Substitution
Deletion
Insertion
Frameshift
What is a point mutation?
A mutation that affects a large segment of a chromosome.
A mutation that occurs when a single nucleotide base is added or deleted.
A mutation that involves the substitution of one nucleotide for another.
A mutation that results in the entire chromosome being duplicated.
What is a frameshift mutation?
A mutation that substitutes one base for another.
A mutation that involves the insertion or deletion of a nucleotide in the DNA sequence.
A mutation that changes an amino acid in the protein.
A mutation that does not affect the protein produced.
T-G-A-C-C-A
T-G-A-G-C-A
Identify the DELETION mutation form the following:
ATG CCA AAT
ATG TCA AAT
ATG CCT AAA T
ATC CA AT

Which type of mutation does the model demonstrate?
Deletion
Substitution
Insertion
Translocation
What mutation has occurred here?
T-G-A-C-C-A
T-G-A-G-C-A
Substitution
Deletion
Insertion
Frameshift
ATTTGAGCC- Original
ATTGAGCC - Mutated
The example above is an example of a

Deletion- Substitution
Deletion -Frameshift
All of the above
