WebDec 17, 2016 · During interphase preceding mitosis, the chromosomes exist in a loose state. At the onset of prophase, proteins associated with the DNA are activated, and the DNA winds around them and bundles in dense shapes. Under a microscope, this stage can be seen as a darkening of different places in the nucleus. WebThis sometimes happens in mitosis, when sister chromatids fail to separate during anaphase. One daughter cell thus ends up with more chromosomes in its nucleus than the other. Likewise,...

WebMitosis is the process of nuclear division by which two genetically identical daughter nuclei are produced that are also genetically identical to the parent cell nucleus (they have the same number of chromosomes as the parent cell); Although mitosis is, in reality, one continuous process, it can be divided into four main stages; These stages are: WebChromosome segregation during mitosis requires a specialized structure called the mitotic spindle. The mitotic spindle is bipolar; the two ends of the spindle are called “poles” and define the spindle long axis. During chromosome segregation the sister chromatids are moved toward the spindle poles (Fig. 2 and Video 1).The major structural elements …
