Variability in rDNA spacer length. (A) A series of hybridization signals depicting the variability in the length for 3′–3′ palindromes. (B) Signals for 5′–5′ palindromes. (C) Bar graphs of the distribution of palindromic signals with respect to the total length between the outer probes, for 5′–5′ palindromes in red and 3′–3′ palindromes in green. The data represent a compilation of measurement on 306 individual palindromes.
