What mutation has occurred here?

T-G-A-C-C-A

T-G-A-G-C-A

• Substitution

• Deletion

• Insertion

• Frameshift

Any change in the sequence of DNA is...

• transgenic shift
• Single Genotype
• Monohybrid Trait
• Mutation

ATT-TGA-GCC- Original

ATT-GAG-CC - Mutated

The example above is an example of a

• Insertion- Frameshift

• Deletion- Substitution

• Deletion -Frameshift

• All of the above

Original DNA: CAT GAT CCA

New DNA: CAT TGA TCC A

What mutation occurred?

• deletion

• substitution

• tranverse

• insertion

Which of the following would result in a frameshift mutation?

• Insertions only
• Substitution only
• Deletion only
• Insertions and Deletions

Are all mutations bad?

• Yes
• No
• Maybe?

Mutated DNA sequences that can be passed from parent to offspring --

• occur in somatic cells (body cells)
• occur in gametic cells (sex cells)
• are rejected by meiosis
• only occur if the parent is exposed to harmful substances

Mutations can be negative because

• They can cause cancer

• They can cause birth defects

• They can help an organism thrive in its environment.

• They can affect offspring.

Mutations can benefit humans because they can:

• Cause illness

• Make an organism more suited to live in its environment.

• Make organisms live shorter lives

• Cause organisms to grow extra limbs.

True or false, mutations create genetic diversity?

• True

• False
