Analysis of DNA repair in XP–HeLa hybrids; lack of correlation between excision repair of u.v. damage and adenovirus reactivation in an XP(D)-like cell line

Hybrids formed between HeLa cells and fibroblasts from xeroderma pigmentosum group D show either HeLa sensitivity or XPD-like hypersensitivity to u.v. radiation and corresponding high or low excision repair capability. Hybrids with low repair are presumed to have lost, via chromosome segregation, th...
