Tandem repeat region in the open reading frame ymf64 amplified from different Paramecium caudatum strains. DNA fragments from strains belonging to the same cox1 haplotype PcCOI_a03 [35] were separated on a 2.0% agarose gel. M, DNA size ladder in kb; lanes a-g, PCR amplified fragments from the different strains. Number of repeat units: (a) 18; (b) 11; (c) 11; (d) 9; (e) 9; (f) 14; (g) 10.
