Term for a Clustering of Virulence Genes on the Chromosome

Question

Term for a clustering of virulence genes on the chromosome of a pathogenic microbe.
A)transposon
B)pathogenicity island
C)operon
D)promoter
E)enhancer region

Accepted Answer

A pathogenicity island is a cluster of virulence genes that are often found on the chromosome of pathogenic microbes. These genes are typically acquired through horizontal gene transfer and can play a critical role in the pathogenesis of the microbe. Transposons, operons, promoters, and enhancer regions are all genetic elements that can be found in or near pathogenicity islands but are not specific to them.
