Figure 4. Switch recombination between Sμ and Sδ.

Figure 4

(a) The schematic map of the CSR of the Cδ gene. Arrows indicate the positions of the Sμ1, Sμ2, Sδ1 and Sδ2 primers. (b) DNA sequence of the recombined Sμ-Sδ junctions. Upper sequence, bovine germline Sμ region (accession no. AY158087); lower sequence, bovine germline Sδ region (accession no. AF411241). The middle sequences are the cloned PCR products. Identical nucleotides are shown by vertical lines. The Sμ and Sδ breakpoints are represented by an inverted triangle and forward triangle, respectively. Overlaps are indicated by boxes.
