Histone code

The histone code refers to a set of chemical modifications on histone proteins, which help package DNA in our cells. Think of histones as spools around which DNA is wrapped. The way these spools are marked (like adding tags or stickers) influences how tightly the DNA is wound and whether certain genes are active or inactive. These modifications can regulate gene expression, impacting everything from cell function to development and disease. In essence, the histone code acts like a language that tells the cell how to read its genetic instructions.
