Question

Given alongside is a diagram representing a stage during the mitotic cell division. Study the diagram and answer the following questions:

1. Identify the stage by giving a suitable reason.
2. Is it a plant or an animal cell? Give a reason to support your answer.
3. Draw a neat, labelled diagram of the stage which follows the one shown in the diagram.
4. How many chromosomes will each daughter cell have after the completion of the above division?
5. Name the four nitrogenous bases.

Answer 1

1. The stage represented in the diagram is Anaphase. In this phase, the two sister chromatids of the chromosomes are pulled apart towards the centrioles present at the opposite poles of the cell.
2. The cell is an animal cell because the cell wall is absent and centrioles are present with asters.
3. Telophase follows Anaphase. Its diagram is shown below:
   
4. Each daughter cell will have four chromosomes.
5. Adenine, Guanine, Cytosine, Thymine
