Question

Sort each process into the appropriate bin to indicate the stage of mitosis in which it occurs. If a process occurs in more than one stage, sort it to the stage when it first occurs.

Answer 1

Mitosis is the cell division in which a single is divided into the two daughter cells. The genetic constituent remain same in this type of division and known as equational division.

Four phases of mitosis are metaphase, prophase, anaphase and telophase. Prophase is the first stage in which the nuclear envelope disintegrates. The cohesion joins the sister chromatid together. In metaphase stage the chromosomes gets arranged at the metaphase plate and microtubules are attached to the kinetochores. The cohesin break downs and the sister chromatid moves towards the opposite poles at the anaphase stage. The telophase stage results in the formation o the nuclear envelope and spindle microtubules disassemble at this stage.
