Table S10: Mutations in the UvrB Gene and Possible Effects

The UvrB gene in every house finch MG strain sampled contains a mutation that truncates the final 3 amino acids of the protein, and this mutation is also present in the closely related TK_2001. The DNA encoding the C-terminal of this amino acid contains a 2 time repeat of the sequence “TAAG” and this mutation introduced one additional repeat of this sequence as a 4 bp insertion. The effect of this 4 bp insertion was to introduce an early “TAA” stop codon and thereby truncate the protein by 3 amino acids as shown below.
