Heteroplasmy in mtDNA Control Region and Phylogenetics of Five Sturgeons
The sequences of the control region (D-loop) of mitochondrial DNA (mtDNA) were obtained from five species of sturgeon. The sequences obtained had lengths between 795-813 bp. The motifs of the conserved sequence block (CBS) and termination-associated sequence (TAS) were identified in the sequences. E...
