Unfortunately the answer is highly dependent on what you mean. In the simplest terms, comparing it directly to how we measure data storage in digital media, the number of different states of a DNA string of length $n$ can have is simply $4^n$. A byte holds $2^8$ different states so the number of bytes in a DNA string of length $n$ is $\frac{n}{4}$. Of ...

This is a very interesting question. Not sure if there is any way to answer without specifying a definition for complexity. It is clear that everything is made of only the same few elements, so complexity must involve more than that. Do the number and position of identical molecules matter? If so, size matters and we would label a large jelly-fish as more ...

Towards practical, high-capacity, low-maintenance information storage in synthesized DNA They show they can get 757,051 bytes or a Shannon information 10 of 5.2 × 106 bits onto 153,335 strings of DNA, each comprising 117 nucleotides (nt). George Church had a similar paper ...
