Practice question
Question
A synthetic mRNA of repeating sequence 5'- CACACACACACACACAC... is used for a cell-free protein synthesizing system like the one used by Nirenberg. If we assume that protein synthesis can begin without the need for an initiator codon, what product or products would you expect to occur after protein synthesis?
Explanation
Mechanistically, nucleic acid structure and recombination involves hairpin formation, Holliday junction resolution and translation control ensure fidelity. This validates one protein, with an alternating sequence of two different amino acids because it matches molecular mechanisms, a pattern repeatedly demonstrated in molecular biology research.
