WebThe eukaryotic pre-mRNA undergoes extensive processing before it is ready to be translated. Eukaryotic protein-coding sequences are not continuous, as they are in prokaryotes. The coding sequences (exons) are interrupted by noncoding introns, which must be removed to make a translatable mRNA. WebThe 5ʹ cap would not be able to be added because it requires the 5ʹ splice site to be functional. B. Splicing would still occur appropriately because the G is not essential at the 5ʹ splice site. C. The U1 snRNA would not be able to …
WebThe three-dimensional shapes of these molecules keep the 5\' end of the RNA away from the enzymes that process the cap. B-Transcription and processing of mRNA occur in the nucleus, where cap binding proteins are found. These proteins, which add and modify the cap, are not found in the cytoplasm, where tRNA and rRNA are transcribed and processed. WebThe 5’ cap is added to the first nucleotide in the transcript during transcription. The cap is a modified guanine (G) nucleotide, and it protects the transcript from being broken down. It also helps the ribosome …

The cap also marks the mRNA to the innate immune system as “self RNA.” the map of tajikistanWebWhat is the function of the 5′ cap? CAP binding proteins recognize the 5′ cap and stimulate binding of the ribosome to the 5′ cap and to the mRNA molecule. The 5′ cap may also increase mRNA stability in the cytoplasm. Finally, the 5′ cap is needed for efficient splicing of the intron that is nearest the 5′ end of the pre-mRNA molecule. tie music meaningWebWhich of the following is not a function of the 5' cap and 3' poly-A tail of a mature eukaryotic mRNA molecule?
