Final answer:
Transposons can serve as substrates for the movement of genes from one location to another, such as antibiotic resistance genes.
Step-by-step explanation:
Transposons may serve as substrates for the movement of genes from one location to another. For example, bacterial transposons can relocate antibiotic resistance genes, moving them from chromosomes to plasmids. This mechanism allows for the colocalization of multiple antibiotic resistance genes on a single R plasmid in bacteria. Such plasmids can then be easily transferred among a bacterial population through conjugation. This allows for the colocalization of multiple resistance genes on a single plasmid, facilitating their transfer among bacteria.
