How is DNA physically collected? What’s revealed? How is it matched to a database of people? And how are samples collected without contamination?
In: Biology
A common misconception about DNA tests is that your DNA is not actually being sequenced. Your DNA contains long repetitive regions which can be “stained” using chemicals, and the length and positions of these regions are unique to every person. That’s how DNA probes can be matched to individuals. But it’s not the case that your entire genome gets analyzed, that would be way too expensive
