Which type of mutation results in the formation of a protein is one incorrect amino acid

The type of mutation that results in the formation of a protein with one incorrect amino acid is called missense mutations. It is a mutation where a single nucleotide changes the results in a codon that codes for a different amino acid.

The correct answer is: missense mutation.

Explanation:

Missense mutations are the ones that occur when the change in the nucleotide sequence of the DNA leads to a different amino acid in a protein because the codon wasn't what it was supposed to be.

The change in one amino acid can make a big difference in a protein, making it lose its function or making it function abnormally -most probably in a way that can be harmful to the cell and the body-.
