Given what you know about gene transfer,which of these transfer methods has the greatest potential to naturally facilitate the creation of pathogenicity islands (PAIs)?

Question

Quizplus · Accepted Answer

Transposition is the only method that can naturally facilitate the creation of pathogenicity islands (PAIs). PAIs are clusters of genes that encode virulence factors, and they are often acquired by bacteria through horizontal gene transfer. Transposition is a type of horizontal gene transfer that involves the movement of a transposon, which is a piece of DNA that can move from one location to another in the genome. Transposons can carry genes that encode virulence factors, and when they insert themselves into the genome of a bacterium, they can create a PAI.
