“…The DNA extracted was quantified using Nanodrop. To analyze TL and mtDNAcn, ß-globulin was used as a single-copy reference gene; primers for specific amplification of telomere repeats and cytochrome c oxidase I (COX I, an mtDNA gene) were selected from previous studies [ 55 , 56 ]. The primer sequences used in this study have been provided in Table 1 .…”
