در این پژوهش تنوع ژنتیکی مرغان بومی گردن لخت با استفاده از تجزیه و تحلیل ژنوم میتوکندری مورد بررسی قرار گرفت. یک قطعه 455 جفت بازی از ناحیه d-loop ژنوم میتوکندری 10 مرغ گردن لخت توالییابی شد. در کل دو هاپلوتیپ شناسایی شد. تنوع هاپلوتیپی و تنوع نوکلئوتیدی در مرغان بومی گردن لخت به ترتیب 01591/0 ± 3556/0 و 002356/0 ± 003133/0 بود. پس از اخذ توالیهای مشابه ژنوم میتوکندری دیگر نژادهای موجود در با...
We investigate the flat phase of quenched disordered polymerized membranes by means a two-loop, weak-coupling computation performed near their upper critical dimension ${D}_{uc}=4$, generalizing one-loop Morse et al. [D. C. al., Phys. Rev. A 45, R2151 (1992); D. and T. Lubensky, 46, 1751 (1992)]. Our work confirms existence finite-temperature, finite-disorder wrinkling transition, which has bee...
BACKGROUND Mitochondrial displacement loop (D-loop) is the hot spot for mitochondrial DNA (mtDNA) alterations which influence the generation of cellular reactive oxygen species (ROS). Association of D-loop alterations with breast cancer has been reported in few ethnic groups; however none of the reports were documented from Indian subcontinent. METHODOLOGY We screened the entire mitochondrial...
The ATP binding cassette (ABC) proteins make up a large superfamily with members coming from all kingdoms. The functional form of the ABC protein nucleotide binding domain (NBD) is dimeric with ATP binding sites shared between subunits. The NBD is defined by six motifs: the Walker A, Q-loop, Signature, Walker-B, D-loop, and H-loop. The D-loop contains a conserved aspartate whose function is not...
The majority of mitochondrial DNA replication events are terminated prematurely. The nascent DNA remains stably associated with the template, forming a triple-stranded displacement loop (D-loop) structure. However, the function of the D-loop region of the mitochondrial genome remains poorly understood. Using a comparative genomics approach we here identify two closely related 15 nt sequence mot...
A growing body of literature suggests that the homologous recombination/repair (HR) pathway cooperates with components of the shelterin complex to promote both telomere maintenance and nontelomeric HR. This may be due to the ability of both HR and shelterin proteins to promote strand invasion, wherein a single-stranded DNA (ssDNA) substrate base pairs with a homologous double-stranded DNA (dsDN...
