Chapter 6. Movement of Resistance Genes ... > Transposition Moves Genes from One D...

Transposition Moves Genes from One DNA to Another

Transposons are mobile DNA elements that reside in DNA molecules. They have discrete ends that help define and identify each element, and they usually carry one or more gene that helps them move to other DNA molecules. (To move from one DNA to another, the donor and recipient DNA must break and rejoin; specific proteins are involved in this process.) When transposons contain an antibiotic resistance gene, they can be easily followed because they cause bacterial cells to be drug resistant. Transposons enable resistance genes to hop from chromosome to plasmid and vice versa. When transposons hop into each other, they can create multidrug-resistant mobile DNA elements.
