Recent advances in molecular techniques allow rapid determination of genetic divergence, and in many circumstances the polymerase chain reaction (PCR) and DNA sequencing have become the technologi...
Genetic diversity and phylogenetic relationship of three Croatian autochthonous cattle breeds was analyzed using a sequence of the mtDNA D-loop region. Among Busha, Istrian, and Slavonian Syrmian Podo...
The mitochondrion contains its own genome. Replication of the mitochondrial DNA (mtDNA) is an essential process that, in most organisms, occurs through the cell cycle with no known mechanism to ensure...
Trypanosoma brucei and related parasites are causative agents of severe diseases that affect global health and economy. T. brucei is responsible for sleeping sickness in humans (African trypanosomiasi...
The contemporary genetic structure of species offers key imprints of how organisms responded to past geological and climatic events, which have played a crucial role in shaping the current geographica...
The aim of this study was to determine the specific polymorphic sites in cattle breeds and inter- and interbreed genetic variation among breeds and to develop a databank of Turkish native cattle mtDNA...
Sardine (Sardina pilchardus) is one of the most important species among Turkish fisheries and is broadly distributed along its coastal waters. In the present study, mitochondrial DNA sequences from th...
摘要线粒体DNAmtDNA)编码线粒体电子传递系统的亚单位以及构建翻译机器所需的各种rRANtRNAmtDNA编码的每一个亚单位都是线粒体完成正常的氧化磷酸化过程所必需的,因此,线粒体DNA的完整性对于生物体的生存十分重要。长期以来,人们一直认为线粒体中不存在DNA的修复。近年来在线粒体提取物中却检测到了一定数量的修复因子,提示线粒体中存在DNA的修复。主要对线粒体修复系统中相关酶的研究进展...
摘要 为了探讨ROS水平与突变的关系,对原发性肝癌线粒体DNA区的突变情况进行研究,同时对原发性肝癌患者组织细胞内ROS进行测定。选择20例原发性肝癌组织及其邻近的癌旁组织,用PCR方法将线粒体DNA D-Loop扩增后测序。组织内ROS的水平采用流式细胞技术测定。结果表明在20对原发性肝癌组织中存在8对mtDNA突变,突变率为40%,共发现突变位点53个,包括2个插入,11个缺失...
摘要 摘要:为了解云南保山猪(Baoshan pig)的遗传多样性及其遗传背景,我们测定了19个个体线粒体DNA D-loop高变区I 15 363~15 801片段序列438 bp。检测到10种单倍型,包括8个多态位点,其中5次T/C转换、1次G/A转换、1次G/C颠换和1次A/T颠换,其A、T、G、C碱基的平均含量分别为35.4%、26.9%、13.2%和24.5%,A+T含量(62.3%)...

期刊信息 篇名 Presence of plastid and absence of mitochondrial DNA in male reproductive cells as evidence for cytoplasmic inheritance in Turnera ulmifolia and Zantedeschia aethiopica 语种 英文 撰写或编译 作者 吉栩,张泉,刘旸...
期刊信息 篇名 A Preliminary Study on the Variability of the mitochondrial DNA control region in populations of finless porpoises, Neophocaena phocaenoides, in Chinese Waters. (In: Biology and Conservation o...
To determine the origin and genetic diversity of Red Chittagong (RC) cattle in Bangladesh, we analyzed mitochondrial DNA displacement loop (D-loop) sequences of 48 samples along with 22 previously pub...
Korean Ogol chicken has been registered as a natural monument in Korea and regarded as a valuable genetic resource for the world. As an initial step to investigate the genetic structures of this breed...
