WebProcessing of tRNA molecules can include all of the following EXCEPT: A. splicing to remove introns in eukaryotes. B. cleavage of large precursors that are cut up into pieces, each containing a single tRNA, in both eukaryotes and prokaryotes. C. template-independent addition of nucleotides at the 5' end in both eukaryotes and prokaryotes. WebSplicing. In many cases, splicing now appears to occur as the transcript is being synthesized. Introns are removed from the pre-mRNA by the activity of a complex called … WebRNA splicing removes the introns, noncoding regions that are transcribed into RNA, in order to make the mRNA able to create proteins. Cells do this by spliceosomes binding on either side of an intron, looping the intron into a circle and then cleaving it off. The two ends of the exons are then joined. eheim classic 2260
