Pathogenicity Islands are Typically Associated With

Question

Pathogenicity islands are typically associated with
A)genes encoding tRNA.
B)genes encoding rRNA.
C)G+C content similar to the rest of the bacterial genome.
D)None of the choices are correct.

Accepted Answer

Pathogenicity islands often contain gene clusters encoding virulence factors, such as toxins and adhesins, which are often flanked by tRNA genes. These tRNA genes are thought to facilitate the integration of the pathogenicity island into the bacterial genome by promoting recombination events.
