A digital illustration showing a strand of DNA (red and blue) wrapped around histone proteins (gray). The DNA strand comprising each chromosome is tightly packed into clusters of wrapped histones to compress the long molecule and streamline separation of copied chromosomes during cell replication. The strand is carefully unwound by different enzymes, including TIP60, to make it accessible for duplication and gene expression.
