Final answer:
The correct experiment to measure cell proliferation and turnover is the 3H-thymidine Incorporation Assay, which tracks cell division by incorporating radioactive thymidine into newly synthesized DNA and measuring it with autoradiography.
Step-by-step explanation:
An experiment to measure cell proliferation and turnover is the C)3H-thymidine Incorporation Assay. This assay involves culturing cells with radioactive thymidine, which the cells incorporate into newly synthesized DNA during cell division. This allows researchers to track DNA synthesis and thereby estimate cell proliferation rates. Autoradiography is used to detect the radioactive labels in DNA, providing a direct measure of the cells that were actively synthesizing DNA. This method was considered creative and informative before the ability to synchronize cells in culture advanced.
In contrast, methods such as DNA microarray analysis, ELISA assays for cell cycle markers, and western blotting for apoptosis markers, while useful for other types of cellular measurements, are not typically used for directly measuring cell proliferation and turnover. Notably, the 3H-thymidine Incorporation Assay not only highlights the cells in S-phase of the cell cycle but also allows calculation of the rate of cell division when used in a series of pulse-chase experiments.
