Transfer Rna (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
- During translation, transfer RNA molecules escort the correct amino acids to the ribosome based on the genetic code specified by the messenger RNA.
- The transfer RNA is shaped in a way that its 5' and 3' ends are positioned for optimal recognition by the cell's translation machinery.
- In the translation process, transfer RNA molecules link amino acids together according to the sequence encoded in the messenger RNA.
- Over 20 distinct types of transfer RNA were found in some organisms, with each being specific to a particular amino acid or group of similar amino acids.
- Transfer RNA initially interacts with the messenger RNA by base pairing with any complementary codon sequence and successfully incorporating the amino acid into the polypeptide.
