Evidence implying DNA polymerase beta function in excision repair.

Comparison was made of the ability of calf thymus DNA polymerases alpha and beta to replicate the following templates: native E. coli CR-34 DNA (T-DNA), calf thymus DNA activated by DNase I (act.DNA), BU-DNA (from E. coli CR-34 cells cultured on BUdR-containing medium) with damages resulting from incomplete excision repair, as well as thermally denatured… CONTINUE READING
