Question

Choose the best answer that describes what is happening during the process of mitosis.

Answer 1

Answer;

The correct answer would be the stage of the cell cycle during which the cell's nucleus and nuclear material divide.

Mitosis or M-phase is one of the phases of cell cycle in which nucleus and its content (genetic material)  divide into two daughter cells.

It sub-divided into various stages namely prophase, metaphase, anaphase and telophase.

Prophase:

• Chromosomes are condensed by the end of this phase.

• Spindle fibers grows and attach to the kinetochores of the chromosomes.

• Nuclear envelope, nucleolus and other organelles disappear.

Metaphase:

• All the chromosomes are aligned at the center of the cell forming the metaphase plate.

• Two kinetochores of each chromosome are attached to the microtubules of opposite spindle poles.

Anaphase:

• Sister chromatids are separated and pull towards opposite poles.

• The cell elongates.

Telophase:

• Cell continues to elongate.

• Nuclear membrane and nucleolus reappear forming two daughter nuclei each with a set of chromosome.

• Chromosome decondense to form chromatin.

It is followed by cytokinesis which results in the formation of two daughter cells.
