4. The nucleotide structure found at the 5' terminus of many eukaryotic messenger rnas, consisting of a 7-methylguanosine connected, via its 5'-hydroxyl group, by a triphosphate group to the 5'-hydroxyl group of the first nucleoside encoded by the DNA; usually symbolised as m7G5'ppp5'N, where N is nucleoside number 1 in the transcribed mrna and is often itself methylated; the cap is added posttranscriptionally.
