Nucleotide genomic signals satisfy regularities that reveal restrictions in the distribution of nucleotides and pairs of nucleotides along DNA sequences. Structurally, a chromosome appears to be more than a plain text, by satisfying symmetry constrains that evoke the rhythm and rhyme in poems. These regularities make it easy to identify exogenous inserts in the genomes of prokaryotes, because such inserts obey different regularities than the background sequence. The paper presents instances of inserts found in the genomes of Bacillus subtilis, Mycobacterium tuberculosis and other prokaryotes. Inserts of exogenous material are frequently accompanied by complementary inserts tending to restore the original constrains.
