D) To aid in the segregation of chromosomes
E) They have no known function.

Question

Quizplus · Accepted Answer

HeT-A and TART transposons in flies are known as telomeric transposons. They help to maintain the length of the chromosome by counterbalancing the loss of chromosomal ends that occurs during every cell division. They provide DNA sequences for the chromosome ends to be maintained and thus play a crucial role in maintaining genome integrity.
