substitution

point mutation
Which type of mutation adds one or more base pairs?

insertion

substitution

deletion

Answer 1

Which result in a frameshift mutation? Check all that apply:
- insertion (yes)
- deletion (yes)
- substitution (no)
- point mutation (usually no — typically refers to a single-base substitution)

Reason: Frameshifts occur when nucleotides are inserted or deleted (not in multiples of three), shifting the reading frame. Substitutions change one base but do not shift the frame.

Which adds one or more base pairs?
- insertion.
