> a single human cell contains 3.2Gb of data in its DNA

DNA is actually closer to 750MB (2.9 billion base pairs, 2 bits to one DNA sequence, so one byte to four sequences). Of course, a cell has other things going on in it (mitochondrial DNA, etc, so overall you're probably still right!

Mitochondrial DNA is only 17k base pairs. More important is the two main DNA copies per cell. But if you really want impressive numbers look at certain species of amphibians and plants that reach the 100 billion base pair range.
