TERF1 · Meander

One of the proteins that caps a chromosome's ends, binding the telomere's repeats so the cell never mistakes a natural end for a broken strand of DNA.

TERF1 is a core component of shelterin, the protein complex that wraps and protects the telomere, the repetitive cap at each end of a chromosome. It binds directly to the telomere's double-stranded TTAGGG repeats, coating the DNA and folding it into a shape the cell reads as an end rather than a break.

By sensing how much telomeric DNA is present, TERF1 also helps set a ceiling on telomere length, holding back the machinery that would extend it. A capped, correctly measured telomere lets a chromosome be copied and separated cleanly; an exposed one trips the alarms a cell reserves for damaged DNA.

TERF1 wraps and caps the chromosome's ends so the cell never reads them as breaks; here the guardian is unwound in turn, its own 1,176-base coding sequence traced off the double helix as a single meandering line across the sheet.

Studio

Genetics of Design is a data art studio that uses pen plotting as its medium. Each piece begins with a public record, whether road networks, genomes, star catalogs, or species data, translated through custom code into composition, density, and line, and published alongside the provenance of the data it came from.
