The core of the histones H2A and H2B can also be modified. Combinations of modifications are thought to constitute a code, the so-called histone code. Histone modifications act in diverse biological processes such as gene regulation, DNA repair, chromosome condensation (mitosis) and spermatogenesis (meiosis).
Bread and Circuses. Bread and circuses became the method that the ruling class of ancient Rome used to maintain their power and control of the people. This method kept their sheep fat and happy, even as they fleeced them and sent them off to plunder the free world.
Rome was dominated by a partnership of three men, known as the First Triumvirate from the Latin words for three and men. The partners were Pompey, Caesar, and Crassus.

In the next eight years Caesar's troops brought Gaul under Roman control.
