Provide a definition of chromatin remodeling, and give two examples of this phenomenon.

What parts of the genome are reversibly methylated? How does this affect gene expression?

What are the possible roles of proteins in histone modification?

What are the roles of the Polycomb and Trithorax complexes in eukaryotic gene regulation?

Provide a brief description of two different types of histone modification and how they impact transcription.

Describe how reversible chemical changes to DNA and histones are linked to chromatin modification.
