title: P nucleotides, hairpin DNA and V(D)J joining: making the connection.
abstract: The fine-structures of V(D)J joining products present a cache of information about the recombination process. Testable hypotheses with predictive value are beginning to provide a surprisingly detailed picture of the joining operation. Here, one feature of V(D)J junctions, the appearance of short palindromic inserts, is discussed, and experimental evidence in support of a joining model involving a hairpin-terminated DNA intermediate will be summarized.
