The story of is a journey from its discovery as a "stainable" substance to the realization that it is the master regulator of our genetic code. Originally named by Walther Flemming in the late 19th century from the Greek word chroma (color)—because it absorbed laboratory dyes—it was initially dismissed as mere "packaging" for DNA. The Century of "Packaging"

For decades, scientists focused almost exclusively on the DNA double helix, believing chromatin's only job was to cram six feet of genetic material into a microscopic cell nucleus. It wasn't until the early 1970s that investigators like Ada and Don Olins used electron microscopy to reveal that chromatin wasn't just a tangled mess; it looked like . These beads, later named nucleosomes , are the fundamental units of our genome, consisting of DNA wrapped around histone proteins .
