Genes, oddly, compromise only a minuscule fraction of it…
““Genes, oddly, compromise only a minuscule fraction of it. An enormous proportion-a bewildering 98 percent-is not dedicated to genes per se, but to enormous stretches of DNA that are interspersed between genes (intergenic DNA) or within genes (introns). These long stretches encode no RNA, and no protein: they exist in the genome either because they regulate gene expression, or for reasons that we do not yet understand, or because of no reason whatsoever (i.e., they are "junk" DNA). If the genome were a line stretching across the Atlantic Ocean between North America and Europe, genes would be occasional specks of land strewn across long, dark tracts of water. Laid end to end, these specks would be no longer than the largest Galapagos island or a train line across the city of Tokyo,””
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
Most of the genome consists of non‑coding DNA, whose functions are largely unknown, challenging the gene‑centric view of biology.
In simple terms: The genome is mostly non‑coding DNA, whose purpose is mostly unknown.

A Different Perspective
Non‑coding DNA may be more than “junk,” but its functions remain elusive.
