How might a transposase be responsible for our ability to ward off infectious disease?

Question

Quizplus · Accepted Answer

Enzymes involved in antibody gene rearrangement may be derived from a transposase encoded by an ancient DNA transposon. This hypothesis, called the transposon hypothesis, suggests that the enzymes involved in the generation of antibody diversity may have evolved from transposase enzymes. These enzymes facilitate the movement of DNA segments and could have been co-opted for the rearrangement of antibody genes, thus allowing us to generate a diverse array of antibodies to fight off infectious diseases.
