We have proposed a model of TLS behind the replication fork to explain the persistence of Ub-PCNA after UV treatment. In this model, Ub-PCNA is left behind at the stalled fork and a new molecule of PCNA is used for replication restart beyond the lesion. This model is not however readily extendable to the situa-tion with HU. simple baked wing recipe
