The histone protein octamer includes four types of proteins: <scene name='60/602771/Histonah2a/1'>H2A</scene>, <scene name='60/602771/Histonah2b/1'>H2B</scene>, <scene name='60/602771/Histonah3/1'>H3</scene> | The <scene name='60/602771/Proteinas/5'>histone protein octamer</scene> includes four types of proteins: <scene name='60/602771/Histonah2a/1'>H2A</scene>, <scene name='60/602771/Histonah2b/1'>H2B</scene>, <scene name='60/602771/Histonah3/1'>H3</scene> and <scene name='60/602771/Histonah4/1'>H4</scene>. Histone proteins are organized in dimers so: | ||
