WebMany prokaryotic RNAs are completely functional and do not require any changes (post-transcriptional changes). What is Monocistronic mRNA? Mono means “one” and cistron means “genes.” An mRNA is said as monocistronic mRNA when it codes for only single proteins; it contains only one genes code on it.
