 One might be tempted to object to the argument above concerning methylation, that whereas methylation is a somewhat transitory state, the underlying four-letter sequence is extremely durable, lasting across many generations. Richard Dawkins (1976) famously emphasized the importance of this durability in arguing for the importance of this stability in evolution, even going so far as to describe genes as “immortal”. So perhaps there is a good reason for understanding “C” as referring to a disjunction.
