So, if the point mutation does not actually change the amino acid that is produced, and in this case, it is known as a silent mutation. Now, a silent mutation can either arise on the non coding region of the DNA or on the coding region of the DNA. And the reason a silent mutation can arise on the coding region of the DNA is because our genetic code is degenerate. 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.
