2022 Phase 2 Molecular Basis of InheritanceCodon-anticodon pairing Medium Question 53 of 200 in Molecular Basis of Inheritance

Against the codon 5′ UAC 3′, what would be the sequence of anticodon on tRNA?

A 5′ GUA 3′
B 5′ AUG 3′
C 5′ ATG 3′
D 5′ GTA 3′

The answer is A.

Solution

The anticodon pairs antiparallel with the codon. For mRNA codon 5′ UAC 3′, the anticodon is 3′ AUG 5′, i.e. written 5′ GUA 3′.
