| Elimination of satellite DNA–binding proteins | Overexpression of satellite DNA–binding proteins | Protein binding to abnormal sites |
| Chromocenters cannot form; chromosomes bleb away from the nucleus in micronuclei | Chromosomes gather in larger bunches than normal, limiting the number of chromocenters formed | All regions in contact with the DNA-binding proteins are pulled into chromocenters |
