This method enabled us to determine frequency of misrecognition of purine bases at the second position of arginine codons (A GR/A AR) in the mRNA. Using this method the fidelity of translation of ribosomes derived from mouse livers was found to remain unchanged from 2 to 29 months, the ...
the specificity determinants apparently reside within their anticodons since the simple exchange of these three bases between the two tRNAs causes a switch in their amino acid identities. Thus, distinct structural features in the different tRNAs may be involved in their recognition by the proper amino...

What does each codon in messenger RNA (mRNA) specify? a. A nucleotide. b. An enzyme. c. An amino acid. d. A promoter. Translation of Protein Synthesis: During translation of protein synthesis, a ribosome attaches itself to a strand of messen...
Changes in synonymous coding can alter mRNA splicing, mRNA folding, and stability6,7,8, and can affect translational speed and accuracy and the conformation of the translated protein9,10,11,12. Numerous studies have shown that changes in the rhythm of translation can alter the kinetics of co-...
Mechanism of codon usage bias in fine-tuning transcription. A: Synonymous mutations cause exon skipping by disrupting sequences of the exonic splicing enhancer (ESE). B: Codon usage bias influences mRNA stability. Synonymous mutations (red triangle) may create recognition sites of microRNAs, resulting...

end of the coding sequence since previous studies have shown that they are required for recognition of the AUG start codon to initiate translation in prokaryotes and eukaryotes, respectively, [43]. At the secondary structure level, it was found that hairpin, stem-loop and pseudoknot mRNA structure...
readthrough rates, we compared stop codon (PTC) readthrough in neurons with those in glia, by expression of the reporters in those tissues specifically. Neurons exhibited higher readthrough than glial cells (Figs.4b,S5). Could differences in NMD and hence reporter mRNA stability explain this ...
