Final answer:
V(D)J recombination involves the use of protein complexes to hold DNA molecules in place while broken ends are repaired by nonhomologous end joining.
Step-by-step explanation:
During V(D)J recombination, DNA molecules are held in place by protein complexes while broken ends are rejoined by DNA repair enzymes using a process called nonhomologous end joining. Nonhomologous end joining is a DNA repair mechanism that directly joins broken DNA ends without requiring a template or sequence homology. This process helps to maintain the structure of the DNA molecule after it has been broken during V(D)J recombination.
