Chromosomal rearrangements due to insertion sequences have apparently contributed to the evolution of several human pathogens.

Question

Quizplus · Accepted Answer

Insertion sequences are pieces of DNA that are capable of moving around a genome and can cause chromosomal rearrangements or mutations. These rearrangements can lead to changes in gene expression or the emergence of new virulence factors, which can contribute to the evolution of human pathogens. This has been observed in several pathogens, such as Salmonella and Mycobacterium tuberculosis. Therefore, the statement is true.
