Inosine in the tRNA anticodon will base pair with all except which one of the following bases in the codon of mRNA?
The principle of nucleic acid structure and recombination explains that hairpin formation, Holliday junction resolution and translation control ensure fidelity. Hence guanine fits best because it matches molecular mechanisms, as documented in authoritative sources on molecular biology.
Ref: Alberts et al., Molecular Biology of the Cell, 6th Edition, Chapter 5, DNA Replication and Repair, discusses Holliday junction formation during homologous recombination and replication fork dynamics ensuring genome duplication.
