WebThe superinduction of histone mRNAs by protein synthesis inhibition is effective at the G1/S border, and in the S-phase and non-S-phase periods of the cell cycle. However, the relative increase in histone mRNA is greater when cells not synthesizing DNA are treated with a protein synthesis inhibitor than when S-phase cells are so treated. WebThe expression of the replication-dependent histone mRNAs is tightly coupled with DNA replication, with significant amounts of histone mRNA present only in S phase.
