Breast Cancer Cells Dividing This confocal micrograph shows two human breast cancer cells dividing. The cell at the top is at prophase, showing the condensing chromosomes prior to their separation. The cell at the bottom is in anaphase, where the chromosomes are in the process of pulling apart. Cancer patients may feel like they have [...]
