Removal of introns
WebMar 7, 2011 · In bacterial, bacteriophage, archaeal, eukaryotic, and organelle genomes, RNAs of very different function (tRNAs, rRNAs, and mRNAs) often contain introns. The correct removal of the introns has been shown to proceed by mechanisms that fall into four classes. 1. Group I self-splicing introns are removed by an autocatalytic mechanism that ... WebMar 27, 2024 · The removal of introns and alternative splicing of exons is an example of post-transcriptional control of gene expression (Option b).. What is posttranscriptional control?

WebRemoval of introns describes which of the following processes in relation to the primary transcript in eukaryotes? 1. Trimming 2. 5' capping 3. Poly-A tailing 4. Splicing Molecular … WebTranscription is the process of creating a mRNA molecule from a gene in the DNA. During this process, a copy of the gene is created on the mRNA molecule. RNA processing is the process of modifying the mRNA molecule to make it ready for translation. This includes the removal of introns, the addition of a poly-A tail, and the addition of a 5' cap.
