Prophase,metaphase,anaphase,and Telophase

Question

Prophase,metaphase,anaphase,and telophase
A) are stages of cytokinesis.
B) occur during G1.
C) are concerned with the synthesis of DNA and the doubling of the chromosomes.
D) are stages of mitosis.

Accepted Answer

Prophase, metaphase, anaphase, and telophase are stages of mitosis, the process of cell division in which a single cell divides into two identical daughter cells. In prophase, the chromatin condenses into visible chromosomes, the nuclear membrane breaks down, and the spindle apparatus begins to form. In metaphase, the chromosomes align at the equator of the cell and attach to spindle fibers. In anaphase, the sister chromatids separate and are pulled towards opposite poles of the cell. In telophase, the chromosomes reach the opposite poles of the cell and begin to decondense, and a new nuclear membrane forms around each set of chromosomes. Cytokinesis, the final stage of cell division, usually occurs in conjunction with telophase but is a separate process that involves the physical division of the cell into two daughter cells.
