Question

Quizplus · Accepted Answer

Studies have shown that approximately 25% of the genome of E. coli O157:H7 has been acquired from other species through horizontal gene transfer, including virulence factors that contribute to its pathogenicity. This acquisition of genes from other organisms has played a significant role in the evolution and adaptation of this bacterium to different environments and hosts.
