The molecular weight of a protein is 30 kDa. The minimal length of mRNA encoding this polypeptide will be close to
In molecular biology, nucleic acid structure and recombination dictates that hairpin formation, Holliday junction resolution and translation control ensure fidelity. Therefore 800 is correct as it matches molecular mechanisms, supported by mechanistic studies and conserved across related systems.
Ref: Lodish et al., Molecular Cell Biology, 8th Edition, Chapter 8, RNA Processing and Translation, covers mRNA hairpins, puromycin mechanism and aminoacyl-tRNA function governing protein synthesis.
