E Correct answer
Explanation

Transposons are mobile segments of DNA that cannot exist independent of a replicon because they don't have an ori of their own. Transposons do not contain their own origin of replication, but rely on the host DNA to provide this feature. Each replicon contains an origin for initiation of replication.
