*Ranking according to occupied base pairs in 5.4 Mb of N. furzeri GRZ as given in column 3. ^†For consensus sequence of one repeat unit, and deduced from sequences of most similar repeat units only. ^‡The 24-nucleotide microsatellite comprises a heterogeneous fraction. The genomic clone used for FISH analysis has a G+C content of 58.1%. ND, not determined.
