Radiation increases the probability that dicentric chromosomes form after every mitosis event , marked by the rupture of an anaphase bridge and the formation of '' tailed '' nuclei , which are protrusions of the nuclei into the cytoplasm .
Radiation increases the probability that dicentric chromosomes form after every mitotic event , which form chromosome bridges in anaphase and telophase . 
 The rupture of chromosome bridges result in the formation of '' tailed '' nuclei , which are protrusions of the nuclei into the cytoplasm .
