Analysis of mitochondrial DNA control region sequences from 41 species of bats representing 11 families revealed that repeated sequence arrays near the tRNA-Pro gene are present in all vespertilionine bats. Across 18 species tandem repeats varied in size from 78 to 85 bp and contained two to nine repeats. Heteroplasmy ranged from 15% to 63%. Fewer repeats among heteroplasmic than homoplasmic in...

The solution structure of the hairpin formed by d(CGCGTTGTTCGCG) has been examined in detail by a wide variety of NMR techniques. The hairpin was characterized by proton NMR to obtain interproton distances and torsion angle information. An energy-minimized model was constructed that is consistent with these data. The hairpin consists of a B-DNA stem of four C-G base pairs and a loop region cons...

The D-loop region is a hot spot for mitochondrial DNA (mtDNA) alterations, containing two hypervariable segments, HVS-I and HVS-II. In order to identify polymorphic sites and potential genetic background accounting for Hypertrophic CardioMyopathy (HCM) disease, the complete non-coding region of mtDNA from 31 unrelated HCM patients and 45 normal controls were sequenced. The sequences were aligne...

The diamondback moth, Plutella xylostella L., is a lepidopteran pest that damages various vegetable plants belonging to the genus Brassica worldwide. Various biological controls, such as parasitoid wasps, have been used control this pest. Among these, Diadegma semiclausum and Diadegmafenestrale are widely globally. In field-based research, investigation of population dynamics parasitoids rate p...

Change in cellular glucose metabolism is considered to be a biochemical hallmark in cancer cells. The mitochondrion is the key organelle in which glucose metabolism occurs. However, whether DNA methylation at the displacement loop (D-loop) region of mitochondrial DNA (mtDNA) has an effect on the expression of the rate-limiting enzyme, and, therefo...

High fidelity homologous DNA recombination depends on mismatch repair (MMR), which antagonizes recombination between divergent sequences by rejecting heteroduplex DNA containing excessive nucleotide mismatches. The hMSH2-hMSH6 heterodimer is the first responder in postreplicative MMR and also plays a prominent role in heteroduplex rejection. Whether a similar molecular mechanism underlies its f...

leber hereditary optic neuropathy (lhon) is a maternally inherited form of retinal ganglion cell degeneration leading to optic atrophy in young adults. it is caused by three primary point mutations including g11778a, g3460a, and t14484c in the mitochondrial genome. these three mutations account for the majority of lhon cases and affect genes that encode for different subunits of mitochondrial c...
