Q. The tRNA anticodon 3-UAC-5 will pair with the mRNA codon :
(a) ‘5-AUU-3’
(b) ‘5-UAC-3’
(c) 5′-AUG-3′
(d) 3′-GUA-5′
Solution :
Correct option : C The codon is a sequence of three bases on mRNA that determines an amino acid. The anticodon is a sequence of tRNA that is complementary to the codon. From the question, first, write the antiparallel sequence for the codon based on the tRNA anticodon. In this example, the anticodon is 3-UAC-5. Thus, the codon would be 5-AUG-3. So, the correct option is C.
