The biological functions of DNA are mediated by specific proteins that interact with it. Proteins "bind" to DNA by targeting those nucleotides.
That is how many key biological functions take place.
Each block in our Blockchain performs a role comparable to that of nucleotides in a DNA molecule. Tokens assume the role of proteins. They are the fibers of a geometric object, like the threads in a piece of cloth. The pattern and even shape of that cloth depend on the number and type of assets mapped into the Blockchain.
Cryptography keeps it all together. It also mediates the binding of the tokens to the Blockchain.
On top of all of this, economic theory helps us rationalise this completely new operational framework, and statistical mechanics provide us with powerful tools for its synthesis.
