What Is DNA?
DNA (deoxyribonucleic acid) is the long, spiral-shaped molecule that stores instructions for how your body is built and operates. It’s made of four chemical bases—A, T, C, and G—arranged in precise sequences that form genes.
We inherit half our DNA from each parent. That’s why families often share traits, from hair colour to disease risk.
Key Concepts
- Genes: Sections of DNA that act like recipes for specific traits or cellular functions.
- SNPs (Single Nucleotide Polymorphisms): Small changes in DNA letters that can influence traits, health predispositions, or how we respond to medications.
- Genotype: The combination of letters you carry for a given SNP (e.g., AA, AG, GG).
- Phenotype: The trait or characteristic that may result from a genotype together with lifestyle and environment.
Why It Matters
Knowing the basics helps you interpret your Unrvl report with confidence. Instead of overwhelming you with jargon, we translate genetic findings into plain English, then reference the underlying science so you can dive deeper when you want.
