And that means more than one codon can basically code for the same exact amino acid. So, if we have a point mutation that causes that forms a new codon, and that new codon still codes for the same exact amino acid, then we know that this is a point mutation because the same exact amino acid sequence will form. On the other hand, a point mutation that changes the codon and the amino acid that is produced is known as a miscense mutation. So, we have two types of point mutations. They can either be silent, or they can be miss sensed. Now, actually, all point mutations are also non frame shift mutations.
