Question
Which one of the following is the correct indication of the stage/phase in the cell cycle?

NTA AbhyasNTA Abhyas 2020

Solution:

The cell cycle is the sequence of events in which the cell divides. It mainly has 4 stages. The G1 stage (cell increases in size), S stage (DNA is doubled), G2 stage (cell prepares to divide) and M stage (division occurs). The M stage further has 4 phases. These are prophase, metaphase, anaphase and telophase. Cytokinesis is the division of cytoplasm while karyokinesis is a division of the nucleus. In the given figure A is karyokinesis, B is anaphase, C is cytokinesis and D is S stage.
