Notice these two amino acids are exactly the same. And that's because our genetic code is degenerate, it's redundant. And that means that more than two codons or more than one codon can basically code for the same exact amino acid, our arginine amino acid. So this is an example of a point mutation that takes place on the coating region on the gene, and that is a silent mutation. That is, it does not produce any type of change. Now, on the other hand, we can have a point mutation that actually causes a change in the amino acid that is produced during the process of translation.
