Insertion sequences (IS) are a type of simple transposable element found in prokaryotic genomes, particularly in bacteria. They are short DNA sequences that can move (transpose) from one location in the genome to another, a process known as transposition. Insertion sequences play a significant role in genetic variability, evolution, and the spread of antibiotic resistance among bacterial populations.
