During which phase(s) of the cell cycle, amount of DNA in a cell remains at 4 C level if the initial amount is denoted as 2C:
| 1. | G0 and G1 | 2. | G1 and S |
| 3. | Only G2 | 4. | G2 and M |
In the 'S' phase of the cell cycle:
| 1. | amount of DNA doubles in each cell. |
| 2. | amount of DNA remains the same in each cell |
| 3. | chromosome number is increased |
| 4. | amount of DNA is reduced to half in each cell. |
Given below is a schematic break-up of the phases/stages of cell cycle-
Which one of the following is the correct indication of the stage/phase in the cell cycle?
| 1. | B-Metaphase | 2. | C-Karyokinesis |
| 3. | D-Synthetic phase | 4. | A-Cytokinesis |
