The present paper describes and example of bacterial IS10 transposition from genome to a plasmid during cloning steps in a laboratory. The database search revealed unusually high frequency of IS10 elements in cloned eukaryotic sequences. It is estimated that approximately every thousandth clone in a database contains an IS contamination. We recommend checking submitted sequences for the presence of IS10 and other IS elements. In addition, DNA databases should be corrected by removing contaminating IS sequences
