Transfer RNA (tRNA) brings amino acids to the ribosome in the correct order during translation.

A tRNA molecule is a single strand of about 70 to 90 nucleotides. Parts of the strand fold back and pair with each other by hydrogen bonds between complementary bases, giving a cloverleaf shape with three loops.
