Why is trna an adaptor molecule

The anticodon pairs with a codon in mRNA ensuring that the correct amino acid is incorporated into the growing polypeptide chain. Four different regions of double-stranded RNA are formed during the folding process. Modified bases are especially common in tRNA. Wobbling between anticodon and codon allows some tRNA molecules to read more than one codon.

If two such tRNAs are brought together peptide bond formation is favoured energetically. Numbers of amino acids are joined by peptide bonds to form a polypeptide chain. This aminoacylation is catalyzed by an enzyme aminoacyl — tRNA synthetase.

This is an endothermic reaction and is associated with ATP hydrolysis. There are no tRNAs for stop codons. Developed by Therithal info, Chennai. Toggle navigation BrainKart. Packaging of DNA helix. DNA Replication. The best answers are voted up and rise to the top.

I can call tRNA using any of its attributes for example "carrier molecule" or "essential molecule" etc. You can check the meaning of "adaptor" in a biological context and see why it fits for tRNA.
