Mutations

Mutations can be negative because

• They can cause cancer

• They can cause birth defects

• They can help an organism thrive in its environment.

• They cannot 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.

A mutation is defined as:

• A change in the cell's structure

• Anything that changes in an embryo

• Any change in the physical features of a human

• A change in the DNA sequence

A mutation in which only one nucleotide is altered is called a:

• Frameshift Mutation

• Deletion Mutation

• Point Mutation

• Insertion Mutation

Another name for a point mutation is:

• Substitution

• Frameshift

• Insertion

• Deletion

Original: A-T-T-T-G-A-G-C-C

Mutated: A-T-T-G-A-G-C-C

The example above is an example of a

• Insertion

• Point mutation

• Deletion

• Substitution

Mutations are random.

• True

• False

Mutations are SOMETIMES helpful to the organism.

• true

• false
