RNAProcessingPost-Transcriptional真核细胞进化The 5' cap is a unique feature of eukaryotic cellular and viral messenger RNA that is absent from the bacterial and archaeal domains of life. The cap is formed by three enzymatic reactions at the 5' terminus of nascent mRNAs. Although the capping ...

What control of gene expression begins when processed mRNA reaches the cytoplasm and before there is a protein product? Which of these processes does not occur in the nucleus? A) DNA replication B) Transcription C) Translation Explain the processes of splicing, capping, and tailing which ...
Transcribe a sequence of DNA to the complementary RNA sequence. What would the sequence of bases of the anticodons on the tRNA be? Fill in the blank: Any three base sequence found on the mRNA that codes for a specific amino acid...
Which of the following is performed by eukaryotic cells during transcription but not in bacteria? a) Polyadenylation b) Splicing exons together after removing unneeded introns c) Adding a guanine nucleotide to the 5' end (capping) d) All of the above ...
Thus, it is a prerequisite for the design of mRNA vaccines to maximize the stability of RNA and translation efficiency and avoid the innate immune response by host cells [44, 45]. Below we will discuss the major strategies used in designing mRNA vaccines, including 5'-capping, nucleoside ...
Pfizer and Moderna’s messenger RNA-based shots were updated totarget a more recent Covid-19 strainknown as KP.2, whileNovavax’s traditional protein-based shot targets a strain called JN.1. The FDA hasn’t yet approved Novavax’s updated shot. Newer strains could be more contagious...
This activity was shown to be the first of four consecutive steps in the conventional RNA capping pathway (reviewed in (Decroly et al., 2012)), leading to the addition of an m7GpppNm-cap to the 5′ end of mRNA. It is employed for mRNA capping by all eukaryotes and, presumably, also...
What is the difference between the process of translation and transcription? What is the region of DNA where sigma factors bind to start transcription called? How are enzymes involved in the process of genetic transcription? Explain the processes of splicing, capping, and tailing which occur during...
Transcription is the process of creating a messenger RNA strand (mRNA) of a gene made of DNA. Once the DNA is transcribed into mRNA, the mRNA is translated into an amino acid sequence that folds into a protein. Answer and Explanation: The ...
