The given structure is the clover leaf model of tRNA which is a adapter molecule that reads the code and binds to the specific amino acids also. It has an anticodon loop ('C') that has the bases complementary to the DNA code. It has an amino acid receptor ('A') end where amino acids bind. 'B' is the T loop and 'F' is the D loop. 'E' represents the codon sequence and 'D' is the anticodon sequence.
