The resolutions of metal-4-(2-pyridylazo)resorcinol chelates by capillary zone electrophoresis (CZE) were investigated in the presence of some interacting reagents; also, equilibrium reactions between the chelates and the interacting reagents were analyzed in an aqueous solution. Among nine metal chelates formed in aqueous solution, the chelates of VV, FeII, CoIII, NiII, and CuII were resolved ...

A large number of studies in evolutionary biology utilize phylogenetic information obtained from mitochondrial DNA. Researchers place trust in this molecule and expect it generally to be a reliable marker for addressing questions ranging from population genetics to phylogenies among distantly related lineages. Yet, regardless of the phylogenetic method and weighting treatment, individual mitoch...

Data obtained from alignments of nucleotide sequences of mitochondrial (mt) DNA molecules of the nematode worms Ascaris suum and Caenorhabditis elegans indicate that in six of the mt-protein genes of A. suum and three of the mt-protein genes of C. elegans TTG is used as the translation initiation codon. Also, GTT seems to be the translation initiation codon of the A. suum COIII gene. All of the...

Despite more than a century of debate, the evolutionary position of turtles (Testudines) relative to other amniotes (reptiles, birds, and mammals) remains uncertain. One of the major impediments to resolving this important evolutionary problem is the highly distinctive and enigmatic morphology of turtles that led to their traditional placement apart from diapsid reptiles as sole descendants of ...

A history of Pleistocene population expansion has been inferred from the frequency spectrum of polymorphism in the mitochondrial DNA (mtDNA) of many human populations. Similar patterns are not typically observed for autosomal and X-linked loci. One explanation for this discrepancy is a recent population bottleneck, with different rates of recovery for haploid and autosomal loci as a result of t...

We had previously shown that sperm from men harbouring haplogroup T mtDNAs swim less vigorously than those from haplogroup H. However, the biochemical basis of this motility was difficult to investigate because of the multiple mutations, the most important of which affected respiratory complex I for which there is no crystal structure. To more thoroughly study the relationship between mtDNA var...

The complete mitogenome of the horse stomach bot fly Gasterophilus pecorum (Fabricius) and a near-complete mitogenome of Wohlfahrt's wound myiasis fly Wohlfahrtia magnifica (Schiner) were sequenced. The mitogenomes contain the typical 37 mitogenes found in metazoans, organized in the same order and orientation as in other cyclorrhaphan Diptera. Phylogenetic analyses of mitogenomes from 38 calyp...

The complete mitochondrial DNA (mtDNA) molecule of the gorilla was sequenced. The entire sequence, 16,412 nucleotides, was determined by analysis of natural (not polymerase chain reaction) restriction fragments covering the whole molecule. The sequence was established from one individual and thus nonchimeric. After comparison with the COII gene of gorilla specimens with known geographical origi...

آتاکسی نخاعی-مخچه ای (sca) از بیماری های ژنتیکی ناهمگون و تحلیل برنده سلول های عصبی است که علائم آن، با تأخیر زمانی، از بدو تولد ظاهر می شوند. این بیماری بر اثر تکرارهای پشت سر هم توالی های نوکلئوتیدی ایجاد می شود. بیماری دارای انواع گوناگونی است که نمی توان آنها را به آسانی و بر اساس علائم بالینی از هم متمایز کرد. یکی از علائم مشترک در تمام انواع بیماری ناتوانی در حفظ تعادل بدن (آتاکسی) است که...
