My identity resembles the complex nature of proteins (and not just because I'm composed of them). Amino acids form unique sequences up to thirty thousand units long through a myriad of finely-tuned biological processes. It seems so improbable that the amino acid side chains should bond to each other in the exact conformation required to produce a three-dimensional, functional protein. Their final form relies on an incalculable number of subunits and external mechanisms. In the same way, I see myself...
