摘要:Two species of H4 histone mRNA were isolated from the polysomes of S phase HeLa S3 cells. 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.
