Question

Identify the stages A and B of mitosis and write a
note on them.

Answer 1

Answer:

There are four stages of mitosis: prophase, metaphase, anaphase and telophase.

1) Prophase: chromatin into chromosomes, the nuclear envelope break down, chromosomes attach to spindle fibres by their centromeres

 2) Metaphase: chromosomes line up along the metaphase plate (centre of the cell) .

3) Anaphase: sister chromatids are pulled to opposite poles of the cell.

 4) Telophase: nuclear envelope reforms, chromosomes unfold into chromatin, cytokinesis can begin The order of the stages of mitosis can be remembered using the mnemonic PMAT.
