- Why are histopathologists interested in the percentage of mitotic cells in a tissue biopsy? 1.High rates of cell division (i.e. a high mitotic index) are characteristic of tumours 2.Low rates of cell division (i.e. a low mitotic index) are indicative of tumours 3.Mature differentiated cells continue to go through the cell cycle 4.They are interested in looking for misshapen cells.Match the following terms with their definition. Note that some of the terms will not be used. 1. S phase 2. Oncogene 3. G0 phase 4. Cyclin 5. Metaphase checkpoint 6. G2 phase 7. G1 checkpoint 8. Cyclin-dependent kinase 9.
