Mutations Review

​Mutations Review

Point/Substitution ​

​

Changes the base at one point.

​

Only affects the one amino acid, possibly changing the one gene

​Gene Mutations

​

Frameshift - Insertion/Deletion

​

Changes how the rest of the codons are read after the mutation​

​

Only affects one gene​

​Gene Mutations

​

Multiple Choice

ATTTGAGCC- Original
ATTGAGCC - Mutated
The example above is an example of a 

• Insertion- Frameshift

• Deletion- Substitution

• Deletion -Frameshift

• All of the above

Multiple Choice

In a point mutation, this would have the worst effect on the function of the protein 

• an insertion or deletion near the end of a gene

• an insertion or deletion at the beginning of the gene

• an insertion at the middle of the gene

• a base substitution

Multiple Choice

Which of the following would result in a frameshift mutation?

• Insertions only

• Substitution only

• Deletion only

• Insertions and Deletions

Multiple Choice

Why is the order of amino acids so important?

• The order of amino acids dictates what shape the protein will fold into.

• It is not important. The protein folding chamber will force the protein to fold into the correct shape.

Multiple Choice

some sources of mutations can be...

• radiation

• chemicals

• viruses

• all of the above

Multiple Choice

Mutations can be...

• Harmful

• Beneficial

• Neutral

• All of the Above

​Chromosome Mutations

​

​Some text here about the topic of discussion.

Multiple Choice

Multiple Choice

Part of a chromosome is reversed.

• Inversion Mutation

• Deletion Mutation

• Translocation

• Point Mutation

Multiple Choice

Part of one chromosome is transported and attached

to a non-homologous chromosome

• Inversion Mutation

• Translocation Mutation

• Duplication Mutation

• Point Mutation

Multiple Choice

Failure of homologous chromosomes

to separate during meiosis.

Results in gametes with either one extra or one missing chromosome.

• Translocation

• Nondisjunction

• Replication

• Transcription

Multiple Choice

Which of the following images is a DELETION?

Multiple Choice

Which of the following statements is a DELETION?

• Produces an extra copy of all or part of a chromosome.

• Reverses the direction of parts of a chromosome.

• Involves the loss of all or part of a chromosome.

• Occurs when part of one chromosome breaks off and attaches to another.

Multiple Choice

Which of the following statements is a TRANSLOCATION?

• Produces an extra copy of all or part of a chromosome.

• Reverses the direction of parts of a chromosome.

• Involves the loss of all or part of a chromosome.

• Occurs when part of one chromosome breaks off and attaches to another.

Multiple Choice

Some mutations can be to the benefit of the species.

• FALSE

• TRUE
