Vodolazhsky3 Patterns of Single Nucleotide Polymorphism Distribution in Hypervariable Regions of the D-Loop of Human Mitochondrial DNA 1State Center 16 of Forensic Medicine and Crime Laboratory Investigations, North-Caucasian Military District, Rostov-on-Don, 344010 Russia2Southern Federal University, Rostov-on-Don, 344090 Russia 3Southern Scientific Centre, Russian Academy of Sciences, Rostov-on-Don, 344006 Russia *ikornienko@ya.ru Received - 2009-08-10; Accepted - 2009-11-26 The D-loop of mtDNA is a noncoding locus actively used as an individualizing marker in molecular genetic research. Uneven distribution of SNPs in the D-loop suggests that the functional load within this region is irregular. The nucleotide sequence analysis was used to evaluate the structural and functional role of various D-loop sites of a single individual's mtDNA and their importance in terms of phylogenetic conservatism. The role of duplication of various D-loop elements (TAS, ETAS, CSB elements) in increasing the reliability of the mtDNA replication initiation and termination is discussed. mtDNA, D-loop, SNP, TAS, ETAS, CSB |
