Fig 1. Distribution of Tn-insertions along the S. aureus genome.

A. Insertions appear uniform all along the genome with no obvious gaps or hot spots. B. Distribution of insertions on each strand reveal no apparent strand bias. C. 2,132 Tn insertions were at identical TA dinucleotides but on opposite strands. The 1066 sites appear to be uniformly distributed across the entire genome.
