Question

leukemia is cancer of the bodys blood forming tissues. a leukemia patients bone marrow produces an abnormally high number of white blood cells that do not function properly. a pharmacology company is trying to develop drugs to regulate the production of abnormal white blood cells. which of the following processes is most likely affected by this new drug? differentiation of stem cells into specialized blood cells checkpoints during the cell cycle cellular respiration in blood cells transport of molecules into and out of cells clear all

Explanation:

Leukemia is a cancer related to abnormal cell production. Cell cycle checkpoints regulate cell division. If these checkpoints are affected (e.g., drugs target them), it can control the over - production of abnormal white blood cells. Differentiation of stem cells into specialized blood cells is more about normal cell development rather than regulating over - production. Cellular respiration in blood cells is about energy production in cells, not directly related to cell number regulation. Transport of molecules into and out of cells is about maintaining cell homeostasis, not cell number control.

Answer:

Checkpoints during the cell cycle
