Although Hox genes contain and are originally named because of the homeobox sequence, not all homeobox-containing genes are Hox genes (other examples include the POU genes and CDX genes). The homeobox encodes for a protein sequence called the homeodomain, which is a DNA-binding domain.
11) Most invertebrates have a cluster of ten similar Hox genes, all located on the same chromosome. Most vertebrates have four such clusters of Hox genes, located on four nonhomologous chromosomes. The process that could have potentially contributed to the cluster's presence on more than one chromosome was ________.
