摘要：

The fluorochrome 33258-Hoechst which binds to DNA and preferentially to A-T-rich regions, inhibits drastically the condensation of the centromeric heterochromatic regions in mouse cell lines. Condensation of all other regions of the chromosomes is also inhibited to some extent. The kinetics of condensation-inhibition of the C-heterochromatin indicates that these regions are being condensed at specific time intervals in the G2 period with a specific order of condensation. The C-heterochromatic regions of mouse chromosomes nos. 9, 12, 14, 15 and 16 condense late in G2 and complete their condensation about 30 min before metaphase. Condensation in G2 of Chinese hamster chromosomes is also inhibited by 33258-H treatment. © 1979.
