Persistence of chromatid damage after G2 phase X-irradiation in lymphoblastoid cells from Gardner's syndrome.

abstract：:The human DNA polymerase lambda (Polλ) is a DNA repair polymerase, which is believed not only to play a role in base excision repair but also to contribute to DNA double-strand break repair by non-homologous end joining. We described here that cellular expression of the recently described natural polymorphic variant o...
