WebUncondensed chromosomes are difficult to separate, and failure to properly segregate homologous chromosomes during mitosis (a phenomenon called nondisjunction) can lead to aneuploidy. Aneuploidy in germ cells is often lethal, and aneuploidy in somatic cells is a characteristic of cancer. Share Improve this answer Follow

WebDNA can unwind from histones. When DNA is wrapped around histones, the genes cannot be transcribed into RNA (and, eventually in protein). So these enzymes come along called HATs, which chemically modify the histones in effect loosening their grip on the DNA.
