Question

Which type of dna mutation results in a change in the reading frame of an mrna?

Answer 1

Answer:

Deletion or insertion

Explanation:

Deletions and insertions are type of mutations that can change the reading frame and thus can alter a gene so that its message is changed. These changes are called frameshifts.

Deletion is a mutation in which a base(or sequence of DNA) is deleted from the DNA.

Insertion is a type of mutation in which a base (or sequence) is added to the DNA.
