Answer:

The correct answer is E) 5-CAA-3.

Explanation:

In translation mRNA sequence is read in 3' to 5' direction by ribosome and tRNA contains anticodon sequence i.e in 5' to 3' direction binds to its complementary codons on mRNA and adds specific amino acid in the chain.

In translation and transcription, uracil comes complementary to adenine nucleotide therefore when mRNA codon is 5' UUG 3' then the anticodon must be in opposite direction and complementary so 3' AAC 5' or 5' CAA 3' would be tRNA anticodon. So the correct answer is E.
