Here's why:
* tRNA structure: tRNA molecules have a specific cloverleaf shape. One end of the tRNA molecule has an anticodon that recognizes and binds to a specific codon on the mRNA molecule. The other end of the tRNA molecule carries the amino acid that corresponds to the codon.
* Role in translation: During protein synthesis (translation), tRNA molecules act as "interpreters" between the genetic code in mRNA and the amino acid sequence of the protein. They deliver the correct amino acids to the ribosome, where they are linked together to form a polypeptide chain.
