Final answer:
A missense mutation is a type of mutation that changes a sense codon into a different sense codon, resulting in the incorporation of a different amino acid. This can affect the structure and function of a protein.
Step-by-step explanation:
A mutation that changes a sense codon into a different sense codon, resulting in the incorporation of a different amino acid is called a missense mutation. This type of mutation substitutes one amino acid for another and may change the structure and function of a protein. An example of a missense mutation is sickle cell disease, which is caused by a point mutation that changes the codon from GAG for glutamic acid to GTG for valine in the hemoglobin gene.
