<span>A cataract is simply the clouding on the lens of the eye that makes it a little more difficult to see, causing some distortion as if looking though a fogged window. Some of these are congenital but generally they are age related due to the lens hardening an thickening as well as a side effect of diabetes. It is likely caused by inadequate delivery of nutrients to the deep lens fibers. Smoking and frequent exposure to intense sunlight increase ones risk for cataracts, but long term vitamin c supplements can help decrease the risk. In order to treat this condition, the lens can be removed and then replaced with an artificial lens.</span>
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.
