Here's why:
* tRNA Structure: tRNA molecules have a unique cloverleaf structure. One end of the tRNA has an anticodon, which can bind to a specific codon on the mRNA. The other end carries the corresponding amino acid.
* Function: During translation, tRNA molecules act like "delivery trucks" for amino acids. They read the mRNA codons and bring the correct amino acid to the ribosome, where it is added to the growing polypeptide chain.
