Question

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

the stage during which the cell carries out normal cellular functions, and makes copies of its DNA.

the stage of the cell cycle during which the cell's nucleus and nuclear material divide.

the method by which a cell's cytoplasm divides, creating a new cell.

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.
