Figure 5. Representative sequences of monomeric 5S rDNA and dimeric 5S rDNA.

(A) Arrangement of eukaryotic 5S rDNA and the illustration of the PCR amplification with 5S primers P₁ and P₂R; (B) Representative sequences of 5S rDNA Class IV and Class V from TC; (C) The dimeric 5S rDNA tandem arrays (NTS–I–N) of 4nRT hybrids. The gene sequences of 5S rDNA are underlined and the shaded regions show the 5S primers. Dashes indicate alignment gaps; asterisks represent variable sites; TATA element (TAAA) is included in box.
