[…] The sequence of MLH1 and PMS1 from each of the strains in was determined in house or taken from publicly available sequence (;; For the in house sequencing, MLH1 and PMS1 coding regions and approximately 200 bp of downstream sequence were amplified by PCR, purified and then sequenced using Big Dye chemistry and an ABI 3730xl DNA Analyzer at the Cornell Life Sciences Core Laboratories Center.Sequences were aligned using the CLUSTALW algorithm , using the resources of the Computational Biology Service Unit from Cornell University, which is partially funded by Microsoft Corporation. Neighbor-Joining trees were constructed based on nucleotide sequences, using PAUP*4.0b10 . For MLH1, the nucleotide site responsible for the D761G polymorphism was excluded from phylogenetic reconstruction; similarly, the site responsible for R818K in PMS1 was excluded. […]
