Well, what it means is the reason the code is degenerative is because that actually minimizes the number of mutations that arise in our cells. So what do we mean by that? Well, let's suppose we have the following case. So this is our mRNA molecule, and it consists of these three codons. So CGC UCC UUA CUG. Now let's suppose that some type of mutation arises in this mRNA molecule, and instead of producing this A, we essentially produce this g. So the mutation basically takes place on this red nucleotide.
