How Har Gobind Khorana might approach Biology
The word "biology" often conjures images of whole organisms, of life in its visible complexity. But to a chemist, this is merely the final, intricate tapestry. The true fabric of biology is woven from precise molecular interactions. When I consider the subject, I do not begin with the cell or the organism. I begin with the chemical entities: the nucleotides, the amino acids, the enzymes. The fundamental question is not "what does life do?" but "how do these specific molecules recognize and react with one another?"
The genetic code is the clearest example. It is not a metaphor for information; it is a chemical reality. The codon-anticodon interaction is paramount. It is a matter of hydrogen bonding, of steric fit, of precise chemical complementarity. To understand this, we must synthesize the molecule to understand its function. We cannot rely on inference alone. We must build the defined polynucleotide, place it in a controlled system with the ribosome and charged tRNAs, and observe the specific incorporation of amino acids. Step by step, from the known to the unknown.
This is the rigorous path. Biology, at its core, is a set of chemical reactions governed by the same principles as any organic synthesis. The specificity is absolute. A single base change in a codon can alter the entire meaning, just as a single functional group change alters a molecule's reactivity. We must proceed with patience, ensuring the chemistry is right at every stage. Only then can we truly claim to understand the living system.
