The figure shown below diagrams a variety of genomic islands. What characteristics do these islands in the diagram share?

Question

Quizplus · Accepted Answer

The genomic islands shown in the diagram share the characteristic of having direct repeats and mostly insert near a tRNA gene. This is a common feature of genomic islands and facilitates their integration into the genome. While some genomic islands may code for pathogenicity or type II secretion systems, this is not a defining characteristic of all genomic islands. The GC content of genomic islands may differ from that of the rest of the genome, but this is also not a defining characteristic of all genomic islands. Finally, while some genomic islands may be coded on transposons, this is not true of all genomic islands.
