Abstract
Mitomycin C-induced sister chromatic exchange and quadriradial formation were studied in chromosomes from Muntiacus muntjac fibroblasts and A9, a transformed mouse cell line. We present the first direct cytological evidence for the induction of true somatic recombination involving homologous chromosomes. Analysis of the quadriradials from Muntjac cells indicates a non-random distribution with respect to the chromosomes involved and with respect to the points of conjunction. Sister chromatid exchange and quadriradial formation may reflect the outcome of repair processes involving a high frequency of homologous exchanges in the interphase nucleus.Entities:
