insertion sequences

in·ser·tion se·quen·ces

(in-sĕr'shŭn sē'kwĕns-ĕz)
Discrete DNA sequences that are repeated at various sites on a bacterial chromosome, certain plasmids, and bacteriophages; insertion sequences can move from one site to another on the chromosome, to another plasmid in the same bacterium, or to a bacteriophage.
