The nanoscopic structure that locks up our genes
The new research shows that, although tightly packed, heterochromatin is perhaps less dense than previously thought. Made up of nucleosomes--roll-shaped bundles of DNA and protein--the heterochromatin is connected by a velcro-like feature called "Heterochromatin Protein 1 (HP1)." This fundamental feature allows the body to "lock down" genes so they cannot be transcribed. "Life as we [...]
