A complete $\kappa$ V gene is formed as a specific V$\kappa$gene is joined to one of the J$\kappa$ segments with the intervening DNA excised; the process is catalyzed by a protein complex called ___________.
A)V(D)J polymerase
B)V(D)J recombinase
C)V(D)J joinase
D)V(D)J ligase
E)ligandase

Question

Quizplus · Accepted Answer

The specific process described is V(D)J recombination and the protein complex responsible for catalyzing this process is the V(D)J recombinase. A is incorrect because there is no such thing as V(D)J polymerase. C is incorrect because the term "joinase" is not widely used and is not the commonly recognized term for the protein complex. D is close but not specific enough; the correct term is V(D)J recombinase, which includes the ligase activity. E ("ligandase") is not a recognized term in this context.
