We used the so-called empirical codon mutation (ECM) matrix to get some insights into the error protection mechanisms in the genetic code. First, using a dimension reduction technique, the codon substitution frequencies and the physicochemical properties of the encoded amino acids are compared. Then, the different levels of error protection in the genetic code are investigated by employing a 4-ary set partitioning scheme. The channel capacities of the set partitions and the level capacities were determined using the ECM channel model. One of the most interesting result which emanated from the capacity analysis is that the capacities of the first two partition levels were found to be identical. This implies that, in a multilevel coding sense, codes of equal code rates would have to be used to encode the two positions. The last codon position carries very little information and can be transmitted without coding.
