Question

Quizplus · Accepted Answer

Transfer RNAs, or tRNAs, are the adapters that allow translation of the four-letter nucleic acid language into the 20-letter protein language. Each tRNA carries a specific amino acid and has an anticodon that matches a codon on the mRNA, allowing for accurate placement of the amino acid into the growing protein chain.
