Answer:
C. They all use a cut and paste mechanism.
Explanation:
DNA transposons can go through a replicative or nonreplicative transposition.
The replicative transposition uses a "copy and paste" mechanism that consists of the introduction of a new copy of the transposable element in a new position, meanwhile <u>the old copy remains in the original position</u>. This determines an increase in the number of copies.
The nonreplicative transposition uses a "cut and paste" mechanism that consists of the cleavage of the transposable element from its position and its <u>insertion in a new position</u> without increasing the number of copies.
Retrotransposons, on the other side, move through RNA intermediates generated by the reverse transcriptase.

<span>The most serious consequence of acute pancreatitis resulting from biliary obstruction is the development of circulatory shock.</span>
<span>In rare cases, acute pancreatitis can lead to necrosis of pancreas tissues. Pancreatic enzymes may get into the bloodstream and cause inflammation and damage to other organs which then can lead to shock, respiratory failure, kidney failure and other complications. This is a very serious situation which can be fatal.</span>
