Mutations

Which type of mutation occurs when there is an addition or removal of a base?

• missense mutation

• nonsense mutation

• frameshift mutation

• point mutation

What type of mutation is shown in the diagram?

• Point mutation - missense

• Frameshift Mutation - deletion

• Frameshift Mutation - addition

• Point mutation - nonsense

A point mutation where one nucleotide base replaces an original nucleotide base

• Inversion Mutation

• Chromosomal Mutation

• Translocation

• Substitution Mutation

Part of a chromosome

is deleted

• Deletion Mutation-Gene

• Translocation

• Deletion Mutation -Chromosomal

• Crossing Over

Part of a chromosome is repeated

• Gene Mutation

• Point Mutation

• Deletion Mutation

• Duplication Mutation

Part of a chromosome is reversed.

• Inversion Mutation

• Deletion Mutation

• Translocation

• Point Mutation

Part of one chromosome is transported and attached

to a non-homologous chromosome

• Inversion Mutation

• Translocation Mutation

• Duplication Mutation

• Point Mutation

What mutation has occurred here?

T-G-A-C-C-A

T-G-A-G-C-A

• Substitution

• Deletion

• Insertion

• Frameshift

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 mutation will cause translation to stop?

• Mutations 1 and 3 only

• Mutation 1 only

• Mutation 2 only

• Muations 1, 2, 3
