What your link is describing is the size of the Genome encoded into bits. In other words, that's the size of the file containing an entire genome compressed into base pairs in order to store the raw base pair encoding on disk as digital data. That is definitively not the measure of the amount of information encoded into the DNA. Nor can you guess at that encoding by modeling DNA base pairs as 2 bits. DNA base pairs aren't bits. They don't define op codes or memory registers. They are read and executed in a complex way that we don't fully understand. They interact with each other in complex ways that we don't fully understand. There's way more information encoded in those base pairs than a simple 2 bits. You can't simply model them that way and declare that there are X Bytes in a genome. DNA isn't digital.
