Mapping of the displacement loop within the nucleotide sequence of Xenopus laevis mitochondrial DNA.
The mtDNA of the African frog, Xenopus laevis, has a triple-stranded displacement loop (D-loop) structure at the origin of heavy strand DNA replication. The major species of displacing strands has a length of 1670 nucleotides, approximately 3 times the length of mouse or human D-loop mtDNA strands. We report experiments that precisely map the termini of the D-loop strand within a revised sequen...
Although the role of nuclear-encoded gene alterations has been well documented in brain tumor development, the involvement of the mitochondrial genome in brain tumorigenesis has not yet been fully elucidated and remains controversial. The present study aimed to identify mutations in the mitochondrial DNA (mtDNA) control region D-loop in patients with brain tumors in Malaysia. A mutation analysi...
alzheimer’s disease (ad) is the most common form of dementia in the elderly in which interplay between genes and the environment is supposed to be involved. mitochondrial dna (mtdna) has the only non-coding regions at the displacement loop (d-loop) region that contains two hypervariable segments (hvs-i and hvs-ii) with high polymorphism. mtdna has already been fully sequenced and many subsequen...
Genetic diversity as an important marker of the ecological status of aquatic ecosystems is considered a unique and powerful tool to evaluate biological communities. In order to evaluate the genetic diversity among golden mullet species (Liza aurata) in the southeast and southwest coasts of the Caspian Sea by D-Loop gene sequencing, a total of 23 fin specimens of golden mullet were collected fro...

The Caspian Sea and its basin (e.g. Anzali wetland) is one of the natural habitats of wild common carp Cyprinus carpio. In this study the genetic structure of this species. In the south-west of Caspian Sea (the Anzali wetland) was investigated using PCR-RFLP analysis of D-loop region. Two hundred of mature fish were collected from 5 stations (40 individuals from each station) including Siahkesh...
BACKGROUND Cynomolgus macaques are indigenous to Asia occupying a range of geographical areas. A non-indigenous population established on Mauritius approximately 500 years ago. Mauritian cynomolgus macaques are recognised as having low genetic diversity compared to Indonesian macaques, from which they originated. As cynomolgus macaques are widely used as a biomedical model, there have been many...
