Polyphyletic origin of the genus Physarum (Physarales, Myxomycetes) revealed by nuclear rDNA mini-chromosome analysis and group I intron synapomorphy

Cyanobacterial tRNA(Leu)(UAA) group I introns have polyphyletic origin.

Self-splicing group I introns in tRNA anticodon loops have been found in diverse groups of bacteria (alpha, beta purple bacteria and cyanobacteria). In particular, the cyanobacterial tRNA(Leu)(UAA) group I introns have attracted considerable attention because of their presumed ancient origin and immobility. In this work, however, we identified tRNA(Leu)(UAA) group I introns in six out of 16 clo...

the analysis of the role of the speech acts theory in translating and dubbing hollywood films

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...

Characterization of the self-splicing products of a mobile intron from the nuclear rDNA of Physarum polycephalum.

We have characterized the splicing products formed in vitro from RNA derived from the mobile group I intron in the nuclear rDNA of Physarum polycephalum, Pp LSU 3. This intron is a close relative of the well known Tetrahymena intron Tt LSU 1, being inserted at exactly the same position in the rDNA and sharing about 90% sequence identity with Tt LSU 1 in the conserved elements characteristic of ...
