The decoding center, situated on the small ribosomal subunit at the interface with the big one, is involved in the recognition and faithful selection of the codon–anticodon tRNA. The distinction between cognate tRNA and near-cognate tRNA happens when mRNA codons are positioned at the A-site, ...
At present, it is unclear which modified ribonucleotides affect mRNA translation fidelity and existing studies are mostly limited to understanding misreading frequencies only at a given codon. Misreading of mRNA codons is also only one type of post-transcriptional mechanism that can alter a polypeptid...
Molecular biologists have discovered that the amino acid sequence in a protein synthesized is based on sets of three nucleotide bases in messenger RNA called codons. In theory, how many different codons in RNA can be formed by various sequences of nucleot ...
Using RNA sequencing, we then reveal that Orb2-upregulated brain mRNAs with abundant Orb2 binding sites have a rare-codon bias. From these Orb2-upregulated mRNAs, we show that rare codons are critical for expression and social behavior function of the G protein-coupled receptor mGluR. Codon ...
and/or 3) pseudouridylation of uridines in the start codons or stop codons of mRNAs could be used to decrease or increase the efficiency of translation of the modified mRNA. It is further contemplated that a single pseudouridyl modification can be performed in an RNA sequence, or that a ps...

It consists of codons. It consists of anticodons. The major type of RNA, mRNA tRNA rRNA plays a significant role in the synthesis of proteins. mRNA is the one that initiates the protein synthesis and it is followed by tRNA and rRNA where the tRNA helps to bring the specific amino acid ...
In summary, biochemical and structural studies of T4 and RB69 RegA have led from inferences of possible motifs in RNA binding to structure guided mutagenesis revealing a unique protein pocket or groove that, in the monomer form, accommodates the many different mRNAs that RegA proteins bind to ca...
