How are specialized (low-fidelity) eukaryotic polymerases selected and switched with high-fidelity polymerases during translesion DNA synthesis?

Specialized DNA polymerases are required in both prokaryotic and eukaryotic cells for bypassing sites of template DNA damage that arrest high-fidelity DNA replication. Recent studies in the literature provide hints of the complexity of DNA switching between polymerases for translesion DNA synthesis (TLS) and those for normal DNA replication.
