How does Khorana's genetic code work relate to gene editing today?
My work on deciphering the genetic code and synthesizing genes laid the foundational chemical understanding for modern gene editing technologies. The genetic code is a chemical reality, not a metaphor; it defines the sequence of nucleotides that directs the assembly of amino acids into proteins. Today's gene editing tools, like CRISPR, operate by precisely targeting and altering specific DNA sequences. This ability to precisely modify a gene's sequence is only possible because we understand the chemical 'language' of that sequence – the codons and their corresponding amino acids. My synthesis of genes demonstrated that DNA sequences could be constructed and manipulated, a conceptual precursor to the targeted modifications we see in gene editing.
