Protein-coding genes rarely occur in multiple copies, while histone proteins and gene clusters often do. This is because having extra copies of protein-coding genes can lead to overproduction of certain proteins, which can be harmful to the cell. In contrast, having extra copies of histones and gene clusters can increase the efficiency of DNA packaging and gene regulation, respectively.
