A tRNA is commonly named by its intended amino acid (e.g. tRNA-Asn), by its anticodon sequence (e.g. tRNA(GUU)), or by both (e.g. tRNA-Asn(GUU) or tRNA Asn GUU ). [ 19 ] These two features describe the main function of the tRNA, but do not actually cover the whole diversity of tRNA variation; as a result, numerical suffixes are added to ...
Eukaryotic mRNA precursors must be processed in the nucleus (e.g., capping, polyadenylation, splicing) in ribosomes before they are exported to the cytoplasm for translation. Translation can also be affected by ribosomal pausing, which can trigger endonucleolytic attack of the tRNA, a process termed mRNA no-go decay. Ribosomal pausing also aids ...

[2] [3] The mRNA sequence is determined by the sequence of genomic DNA. [4] In this context, the standard genetic code is referred to as 'translation table 1' among other tables. [3] It can also be represented in a DNA codon table. The DNA codons in such tables occur on the sense DNA strand and are arranged in a 5 ′-to-3 ′ direction.
During the translation, tRNA charged with amino acid enters the ribosome and aligns with the correct mRNA triplet. Ribosome then adds amino acid to growing protein chain. Every mRNA consists of three parts: a 5′ untranslated region (5′UTR), a protein-coding region or open reading frame (ORF), and a 3′ untranslated region (3′UTR).
In 1971, Kim et al. achieved another breakthrough, producing crystals of yeast tRNA PHE that diffracted to 2-3 Ångström resolutions by using spermine, a naturally occurring polyamine, which bound to and stabilized the tRNA. [61] For a considerable time following the first tRNA structures, the field of RNA structure did not dramatically advance.
