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.

On the day of the games, the gladiators were ceremoniously led in and paraded around the arena before presenting themselves at the emperorâs podium.

Then the fight was begun in earnest with a variety of weapons.
