16S and 28S phylogenies of three Waldo species

28S ribosomal RNA is the eukaryotic nuclear homologue of the prokaryotic [invalid/archaic clade] 23S ribosomal RNA. This is the structural RNA for the large component of eukaryotic cytoplasmic ribosomes, and thus one of the basic components of all eukaryotic cells.[1]

The genes coding for 28S rRNA are referred to as 28S rDNA. Sequences from these genes are sometimes used in molecular analysis to construct phylogenetic trees.[2]
