| Q.9 | The cell cycle stages for a cultured mammalian cell line require the following periods: G1 = 8 hr, S = 5 hr, G2 = 1 hr, M = 1 hr. An asynchronous culture of these cells is exposed to radioactive thymidine for five minutes and then allowed to continue to grow in nonradioactive medium. The figure below shows the results. If the length of G2 were increased by one hour, which of the following statements would be true regarding the slope of the line from the first appearance of labelled mitotic cells until all cells are labelled? | |
| Ans | 1. It would increase. | |
| 2. It would decrease | ||
| 3. It would stay the same. | ||
| 4. It would switch from a positive to a negative slope |
