Types of Point Mutations

This set of flashcards covers the different types of point mutations along with their definitions and impacts.

Silent Mutation

A change in DNA that does not change the amino acid, so the protein remains the same.

Missense Mutation

A mutation that causes a different amino acid to be added, potentially changing how the protein functions.

Nonsense Mutation

A mutation that creates a stop signal in the DNA, causing the protein to be made too early.

Impact of Missense Mutations

Can change how a protein functions due to the substitution of one amino acid.

Impact of Nonsense Mutations

Generally more serious than missense mutations because they result in a shorter and usually unusable protein.

Impact of Silent Mutations

Have the least impact since they do not alter the protein produced.
