Question

For fruit flies, N=4 and 2N=8 a. Sketch a dividing fruit fly cell which is in prophase I. b. Sketch a dividing fruit fly cell which is in metaphase of mitosis. A 35 year old man developed increasing pain in his left thigh and a marked limp, over 3 weeks. Five years he had undergone a nephrectomy for a renal carcinoma. An isotope showed metastasis in his right lateral ribs and left femur and he had been taking sunitinib. Assuming you are the attending physician, what is the most appropriate next step in his management?
