Trna (Noun)
Meaning
RNA molecules present in the cell (in at least 20 varieties, each variety capable of combining with a specific amino acid) that attach the correct amino acid to the protein chain that is being synthesized at the ribosome of the cell (according to directions coded in the mRNA).
Classification
Nouns denoting substances.
Examples
- Transfer RNA molecules play a crucial role in protein synthesis by carrying amino acids to the ribosome for assembly into a polypeptide chain.
- During translation, tRNA molecules recognize and bind to specific codons on the mRNA, allowing them to position the corresponding amino acid for peptide bond formation.
- The tRNA molecules have distinct regions that allow them to interact with the ribosome, the mRNA, and the amino acid, ensuring accurate translation of the genetic code.
- Each type of tRNA is capable of binding to a specific amino acid through an enzyme-catalyzed reaction, allowing the tRNA to deliver the correct amino acid to the growing protein chain.
- The specific base pairing between the tRNA and the mRNA is critical for accurate translation, as it ensures that the correct amino acid is incorporated into the protein at the correct position.
