Comparison of the 5 ' flanking regions of the mouse J kappa elements , including the conserved putative recombination target sequences , shows no obvious differences consistent with the variation in recombinational efficiency , so we conclude that , although the consensus heptamer and nonamer signals may be sufficient to identify a recombination site , the probability that that site will be used depends also on other determinants .
