Correct splicing of a group II intron from a chimeric reporter gene transcript in tobacco plastids
An in vivo test system was developed to study group II intron splicing in higher plant chloroplasts. The chimeric reporter gene uidA was constructed by translational fusion of an intron-containing segment of the plastid atpF gene with the coding region of a plastid uidA reporter gene. The chimeric uidA gene was inserted into the tobacco plastid genome by the biolistic transformation procedure u...
متن کاملPolycistronic trypanosome mRNAs are a target for the exosome
Eukaryotic cells have several mRNA quality control checkpoints to avoid the production of aberrant proteins. Intron-containing mRNAs are actively degraded by the nuclear exosome, prevented from nuclear exit and, if these systems fail, degraded by the cytoplasmic NMD machinery. Trypanosomes have only two introns. However, they process mRNAs from long polycistronic precursors by trans-splicing an...
متن کاملfeatures of short story in translated and non-translated literature: a polysystemic perspective
ترجمه متون ادبی در دنیای امروز از اهمیت ویژه ای برخوردار است. فرهنگ های مختلف با استفاده از متون ادبی ملل و فرهنگ های دیگر سعی در غنی کردن فرهنگ و ادبیات کشور خود دارند. کشور ما نیز از این قاعده مستثنی نیست. در ایران، ترجمه متون ادبی اروپائی که با دوران مشروطه ایرانی آغاز می شود موجب تغییرات اساسی در فرهنگ، شیوه زندگی و تفکر ایرانیان شده است. در این دوران نه تنها در امورات سیاسی و فکری کشور تغی...
15 صفحه اولA specific endoribonuclease, RNase P, affects gene expression of polycistronic operon mRNAs.
The rnpA mutation, A49, in Escherichia coli reduces the level of RNase P at 43 degrees C because of a temperature-sensitive mutation in C5 protein, the protein subunit of the enzyme. Microarray analysis reveals the expression of several noncoding intergenic regions that are increased at 43 degrees C compared with 30 degrees C. These regions are substrates for RNase P, and they are cleaved less ...
