DNA sequencer

As explained in Data for All

A DNA sequencer is an instrument that processes biological samples to determine their DNA sequences.

A DNA sequencer processes a biological sample by breaking DNA into hundreds of millions of fragments, copying each fragment repeatedly, and reading how the pieces fit together. Repeating this analysis builds a detailed picture of a person’s genome. section 1.2.1

Sequencing can reveal highly personal information: a complete genome remains an ultimate personal identifier even after names, addresses, and demographic details are removed. That makes genetic data valuable—and difficult to truly deidentify—as consumer testing expands. section 1.2.1

How Data for All covers it

How deep it goes
Explains fragment decomposition, repeated copying, and analysis, but stops short of instrument mechanics.
Examples
Uses a submitted sample, millions of DNA fragments, repeated copying, and consumer ancestry and health databases.
What you can do after
Evaluate how sequencing turns a biological sample into identifying genomic information and why removing names cannot ensure anonymity.
How it connects
Links DNA sequencing with genomes, genetic testing, genetic data, deidentification, and consumer ancestry and health databases.
