Electrophoresis under denaturing and nondenaturing conditions indicates that the two H4 mRNAs differ in size. Both mRNAs translate H4 histones in vitro, lack poly(A) at their 3' termini, and are capped at their 5' termini. Polyacrylamide gel electrophoresis and tryptic peptide analysis suggest that the polypeptides synthesized by the two mRNAs are indistinguishable.en-USCell CycleHela CellsHistonesHumansMolecular WeightNucleic Acid ConformationPolyribosomesRNA CapsRNA, MessengerCell BiologyJournal Articlehttps://escholarship.umassmed.edu/stein/1731728478stein/173
