Abstract excerpt
The present study characterizes the satellite DNA of the cave beetle Pholeuon proserpinae glaciale which represent about 3-5 % of its genome, and which is composed of monomers of 266 bp and 70.5 % A-T. Concerted evolution seems to act on a higher-order repeat, a dimer, composed of two types of 266-bp monomers that differ in three diagnostic sites. These dimers show a striking nucleotide identity (98.7 %...
