This article only touches on it but the data stored is far more than just the base pairs. DNA is like a computer program that when it runs, it provides feedback for the code and determines which parts of it should run. It can also modify the code (DNA methylation). Then add on top the external environment - external molecules can interact with the machinery which then impact which code is executed. If code is self-regulating, the amount of information it encodes is far higher than that defined by its base pairs.
