Schematic comparison of the control elements involved in the transcription of the 5S rDNA. Sequences up and down represent the internal control regions (ICRs) and sequence elements of D. melanogaster (D. m) and X. laevis (X. l), while sequences in the middle represent the consensus crustacea and G. Pollicipes orthologues. Similarities respect to the consensus sequences are denoted by asterisk (*).
