Quizplus · Accepted Answer

The highly basic histone proteins are made of the histone fold that consists of three ? helices connected by two loops. Additionally, each core histone has an N-terminal tail which, along with the rest of the protein, can be modified post-translationally. Each nucleosome core particle contains eight histone proteins, two copies of each type. The less well conserved histone H1 is not part of the nucleosome core, but is present in the 30-nm fibers.
