Final answer:
Replicative and nonreplicative transposition involve the movement of DNA transposons. Replicative transposition inserts a new copy while leaving the original copy in place, while nonreplicative transposition completely excises the transposon.
Step-by-step explanation:
Replicative and nonreplicative transposition share a common feature in that they both involve the movement of DNA transposons from one location to another. Both mechanisms require the enzyme transposase to catalyze the transposition process. In replicative transposition, a new copy of the transposon is inserted into the genome while a copy of the original transposon remains at its original location. In nonreplicative transposition, the transposon is completely excised from its original location and then inserted into a new site.
