Composite transposons differ from insertion sequences because they:
Show answer and explanation
Correct answer: Carry additional genes such as antibiotic resistance
Composite transposons are flanked by two insertion sequences and carry additional genes — most famously antibiotic resistance genes such as those on Tn10 (tetracycline resistance). The flanking IS elements supply the transposase needed for movement.
