Answer :
A gene coding for virulence factors proteins is likely to be found in a genomic island of a pathogenic bacterial strain and not found in a nonpathogenic strain.
Genomic islands are clusters of genes that are present in some strains of a bacterial species but not others. These islands often contain genes that confer an adaptive advantage to the bacteria, such as antibiotic resistance, metabolic capabilities, or pathogenicity. In the context of pathogenic bacterial strains, genomic islands frequently carry genes that encode for virulence factors proteins that enable the bacteria to cause disease in a host organism.
Virulence factors can include a variety of proteins, such as adhesins, which help bacteria attach to host cells; toxins, which can damage host tissues; and enzymes that may help the bacteria evade the host's immune response. The presence of these genes in a pathogenic strain and their absence in a nonpathogenic strain suggests that they play a role in the ability of the pathogenic strain to cause disease.
Therefore, when comparing pathogenic and nonpathogenic strains of bacteria, one would expect to find genes coding for virulence factors in the genomic islands of the pathogenic strain, as these proteins contribute to its ability to infect and harm a host.
