Answer:
The correct answer is option A. "V(D)J recombination is similar to the replicative transpositional mechanism".
Explanation:
V(D)J recombination and the replicative transpositional mechanism are very different biological processes. V(D)J recombination is an unique mechanism that takes place by somatic recombination and results in the highly diverse repertoire of antibodies. On the other hand, the replicative transpositional mechanism takes place when a transposable element is duplicated during replication.
