Question
The diagram given below represents a stage in mitosis.
- Identify the stage given above.
- Give one reason to support your answer in (a).
- Mention the number of chromosomes given in the diagram.
Solution
- Anaphase
- Anaphase is characterised by the splitting of centromeres and the separation of chromatids, which move to opposite poles. This is readily obvious in the image provided. Hence, it is anaphase.
- The image contains eight chromosomes. The parent cell contained four chromosomes, which duplicated throughout the synthesis phase. During anaphase, they break and divide themselves evenly between the two daughter nuclei, resulting in each new cell having the same four chromosomes as the original.
