Abstract:
The study of chromosome damage in rodents living on hazardous-waste sites may provide evidence of important biological consequences of chronic exposure to toxic chemical wastes. This study compared bone-marrow cells of animals (Sigmodon hispidus) taken from two superfund waste-disposal sites with those from an uncontaminated site and demonstrated that both populations exposed to hazardous wastes had significantly more structural and numerical aberrations than the control population.

Chromosome Structure
The centromere is a DNA sequence that links sister chromatids. This is also where kinetochores, protein complexes to which spindle microtubules attach, are constructed after the chromosome is replicated. The kinetochores allow the spindle microtubules to move the chromosomes within the cell during cell division.
Telomeres consist of non-coding repetitive nucleotide...

Lampbrush Chromosomes
LBCs are made up of two pairs of conjugating homologous chromatids. Each chromatid consists of alternatively positioned regions of condensed-inactive chromatin and loosely placed-active side loops, which can be contracted and extended. The loops...
