They call it random, but not to what degree. If the distribution is stable it just sounds like code reuse to me.

Living organisms usually read the DNA code in a very strict and predictable way. Every codon, which is a set of three nucleotides in a gene, corresponds to one specific amino acid that becomes part of a growing protein.

Researchers at the University of California, Berkeley have now discovered that one type of microorganism can tolerate uncertainty in this process. Their work challenges a long-held belief that the genetic code must always be interpreted with complete precision.
