WebOct 27, 2014 · Chromosomes are composed of thin chromatin threads called Chromatin fibers. These fibers undergo folding, coiling and supercoiling during prophase so that the chromosomes become progressively thicker and smaller. Therefore, chromosomes become readily observable under light microscope. WebIndividual homologous chromosomes are spatially segregated into haploid chromosome sets along the centrosome axis in an antipairing configuration. Disruption of the antipairing pattern occurs in cancer cells. However, little is known about how this spatial organization of chromosomes is established or maintained.
