The ‘quartet model’ explains how the protein products of the ABCE-function genes might interact to control floral organ identity. Following statements are based on this model. Which one of them is incorrect?

#SCPH01 Biochemistry
  1. There are four combinations of floral MADS-box proteins. SEP proteins may form heterodimers with A (AP1) and B (AP3/ PI) proteins (for petals), B (AP3/PI) and C(AG) proteins (for stamens), and C (AG) protein (for carpels).
  2. All these genes, with the exception of AP2 (and its homologues), are MADS-box genes, a broad family of eukaryotic genes that encode transcription factors containing a highly conserved DNA-binding domain (MADS domain).
  3. The protein quartets are transcription factors and may function by binding to the promoter regions of target genes.

  4. According to the model, one dimer of each tetramer recognize two different sites on the same DNA strand, thus bringing these areas into proximity via DNA-bending.
