For 10 points, name this conserved gene family that controls the anterior-posterior axis of embryonic development.
A non-coding RNA, HOTAIR, trans-silences one of these genes by binding to PRC2, a Polycomb-group protein. These genes code for proteins that bind a TAAT-containing sequence with a 60-amino acid helixturn-helix domain. The (*) chromosomal order of these genes parallels their patterns of expression. In arthropods, segment polarity, gap, and pair-rule genes control their expression, and mutations in them can cause wrong placement of body segments.
