Faucaria bosscheana

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Faucaria bosscheana has left across the world's sequence archives.

The complete instruction manual Faucaria bosscheana carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.
