Solution

The correct option is D 5' AAU 3'
Transfer RNA has an anticodon loop with a three-base sequence that base-pairs with mRNA codons. The mRNA codon is read in 5'-->3 direction and the first base of the codon in mRNA pairs with the third base of the anticodon. Therefore, codon for anticodon 3' UUA 5' is 5' AAU 3'. Codon and anticodon are never read in the same direction; an anticodon with 3' UUA 5' can not have a codon with 3' UUA 5' which makes option B wrong. RNA has uracil (U) in place of thymine; option C is wrong. Adenine never pairs with guanine; option D is wrong. The correct answer is A.
