The number of recombinant E. coli clones containing the PCR fragment from each of the GFP+ clone that were sequenced are shown in brackets. Sequences of six recombinant E. coli clones were determined for the GFP+4 clone and 5 for the rest.
NHEJ mutants with bp deletions at the CCR5 locus are depicted by dashes (-), While mutants with bp insertions are shown by bold type and lower case letters.
