Decoding Your Future: How Your DNA Sequence Could Dictate Your Prescriptions
Decoding Your Future: How Your DNA Sequence Could Dictate Your Prescriptions Imagine a world where your doctor knows exactly which medication will work best for you, and at what dose, before you even take the first pill. This isn't science fiction; it's the promise of pharmacogenomics , a rapidly evolving field that explores how your individual DNA sequence influences your response to drugs. Instead of a one-size-fits-all approach, your unique genetic blueprint could soon be the ultimate guide for your future prescriptions. At the heart of this revolution is our understanding of DNA structure . The familiar double helix, with its sequence of adenine (A), guanine (G), cytosine (C), and thymine (T), holds the instructions for every protein in our body. These proteins include enzymes that metabolize drugs, receptors that drugs bind to, and transporters that move drugs in and out of cells. Variations in your DNA sequence, even subtle single-letter changes called SNPs (Single Nuc...
