Figure 3From: Exonuclease activity and P nucleotide addition in the generation of the expressed immunoglobulin repertoireInfluence of W and S motifs on nucleotide loss. IGHJ genes were grouped by the presence of W and S motifs within the first 15 nucleotides of the IGHJ subgroup sequence. Average exonuclease loss was examined for the three sets; 5' W only, 5' S only and S then W.Back to article page
