The difference(s) between mRNA and tRNA is/are that I. mRNA has a more elaborate 3-dimensional structure due to extensive base-pairing. II. tRNA has a more elaborate 3-dimensional structure due to extensive base-pairing. III. tRNA is usually smaller than mRNA. IV. mRNA contains the anticodon, but tRNA contains the codon. Choose the correct combination.

Answer: (B)
