Interduplex crosslinks by a bifunctional anthramycin DNA crosslinker produced triradial and quadriradial chromosomes. The crosslinker alkylates guanine at N-2. Bovine chromosomes contain GC-rich density satellite DNAs at the centromeric heterochromatin and is the basis for the formation of triradial and quadriradial chromosomes at the centromeres. The in(More)
The distribution of bovine satellite DNA was examined in Madin-Darby bovine kidney cells for each hour of interphase. Cells were grown on coverslips and probed using biotinylated cloned fragments of bovine satellite I DNA. Hybridization was detected using a streptavidin-alkaline phosphatase conjugate. Cells were projected onto a grid of fixed dimensions and(More)
Madin-Darby bovine kidney (MDBK) cells were treated with the bifunctional DNA cross-linker, L-7, to examine the generation of micronuclei and other nuclear abnormalities. The preceding paper demonstrates that L-7 treatment induces the formation of triradial and quadriradial chromosomes in MDBK cells. These chromosomes are believed to result from interduplex(More)
