Ribozyme length
Webb31 okt. 2016 · Group I introns in nuclear ribosomal RNA of eukaryotic microorganisms are processed by splicing or circularization. The latter results in formation of full-length circular introns without ligation of the exons and has been proposed to be active in intron mobility. We applied qRT-PCR to estimate the copy number of circular intron RNA from the … WebbIn each of two reaction tubes, place 6 µL of 10 µ M ribozyme, 3 µL of 10 µ M 32 P-5′-end-labeled substrate, and 3 µL of 500 m M Tris-HCl, pH 7.5, 1 m M EDTA. 2. Seal the tubes, place in an 85°C water bath for 2 min, and then place into a water bath at the reaction temperature (e.g, 37°C). 3.
