OBS are the observed and EXP the expected numbers of repeats of a given length, based on genome size and overall base composition (see Materials and Methods). Expected numbers greater than observed numbers are given in boldface. Significant deviations from expected values at the 0.01 and 0.001 levels are indicated by + and ∗, respectively. The genomic locations of three of the long monoculeotide repeats were identified by blast searches: (G)₁₉: 77 bp 5′ to M. genitalium polC DNA polymerase III (U39681); (A)₁₆: 211bp 5′ to M. pneumoniae: putative lipoprotein (MPAE000039); (T)₁₆: 143 bp 3′ to M. penumoniae putative lipoprotein (MPAE000002).
