The nonsense mutation is a point mutation that produces a stop codon when replacing a single base. The resulting protein is shorter than it shuld be.

What are the types of point mutations?

When a change occurs in a single base pair, it is known as a point mutation.

Points mutations might be either silent, missense, or nonsense.

In silent mutations, the resulting mRNA codon codes for the same amino acid as the unmutated sequence.

However, if the mutation causes the mRNA codon to code for a different amino acid, this mutation is a missense mutation.

Finally, if the mutation causes the mRNA codon to be a stop codon, we are referring to a nonsense mutation.

Nonsense mutations have the ability to put an end to protein synthesis earlier than they should. The production of a mutated stop codon makes the new protein to be shorter.
