WebSep 17, 2024 · mRNAs and tRNAs are transcribed separately from different genes (and in eukaryotes this is even done by different RNA polymerases). These two molecules do interact during during translation — aminoacyl-tRNAs (that is tRNA bound to the appropriate amino acid) bind to codons on an mRNA that is loaded onto a ribosome.

WebJul 18, 2024 · The tRNA key for an mRNA codon is called an anticodon. When a tRNA molecule holds the key that matches a three-nucleobase code it can open the door, drop off its load (an amino acid), and leave the ribosome factory to collect another amino acid load. This will always be the same type of amino acid as the anticodon. WebDec 17, 2024 · Transfer tRNAs (tRNAs) are small non-coding RNAs that are highly conserved in all kingdoms of life. Originally discovered as the molecules that deliver amino acids to the growing polypeptide chain during protein synthesis, tRNAs have been believed for a long time to play exclusive role in translation. However, recent studies have identified key roles …
