01Narrative

Arctostaphylos nortensis, common name Del Norte manzanita, is a shrub narrowly endemic to the mountains along the Oregon/California state line. It has been reported from only 3 counties: Del Norte County, California; and Curry and Josephine Counties in Oregon. The plant grows in chaparral and open forests at elevations of 400 -.

05DNA & barcodingmolecular

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 Arctostaphylos nortensis has left across the world's sequence archives.

06Genome at a glanceCCDB

The complete instruction manual Arctostaphylos nortensis 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.

Chromosomes & ploidyhow the DNA is packaged

2n is the full chromosome count in a normal body cell; n is a gamete (egg or sperm), which carries half. Ploidy is how many complete chromosome sets each cell holds — 2× (diploid) is typical for animals, while higher levels (polyploidy) are common in plants.
