Test: The Cell Cycle MCQ Quiz! Trivia

The correct order of the stages of the cell cycle is III, VI, I, IV, II, V. This means that stage III comes first, followed by stage VI, then stage I, stage IV, stage II, and finally stage V.

Interphase and cytokinesis are not stages of mitosis. Interphase is the phase where the cell prepares for division by growing and replicating its DNA. Cytokinesis is the final stage of cell division where the cytoplasm divides to form two separate daughter cells. Mitosis consists of four stages: prophase, metaphase, anaphase, and telophase. In prophase, the chromosomes condense and the nuclear envelope breaks down. In metaphase, the chromosomes align at the center of the cell.

The correct order of mitosis is prophase, metaphase, anaphase, telophase. During prophase, the chromosomes condense and become visible. In metaphase, the chromosomes line up along the equator of the cell. In anaphase, the sister chromatids separate and move towards opposite poles of the cell. Finally, in telophase, the chromosomes reach the poles of the cell and decondense, and a new nuclear envelope forms around each set of chromosomes.

Chromosomes are structures found in the nucleus of cells that carry genetic information. They are made up of DNA, which contains the instructions for building and maintaining an organism, and proteins, which help in organizing and packaging the DNA. The DNA-protein complex forms a structure called chromatin, which condenses and forms visible chromosomes during cell division. Therefore, the correct answer is DNA and proteins.

Metaphase is the phase of mitosis or meiosis in which the chromosomes align along the equatorial plate of the cell. This is a crucial step before the separation of chromosomes during anaphase. In metaphase, the chromosomes are fully condensed and attached to the spindle fibers, preparing for their distribution to the daughter cells.

At the end of the cell cycle, there are 2 daughter cells. This is because during the cell cycle, a single parent cell divides into two identical daughter cells through the process of cell division, specifically cytokinesis. Each daughter cell contains a complete set of genetic material and is capable of carrying out its own functions and replicating independently. Therefore, the correct answer is 2.

Mitosis is not the result of uncontrolled division of cells. Mitosis is a highly regulated process that occurs in eukaryotic cells to ensure the proper division and distribution of genetic material. It is a crucial process for growth, development, and tissue repair. Uncontrolled cell division is characteristic of cancer cells, where mitosis is not properly regulated. Therefore, the given statement is false.

During anaphase, the sister chromatids are being pulled apart. This is the stage of cell division where the chromosomes are split and move towards opposite poles of the cell. The spindle fibers attached to the centromeres of the sister chromatids contract, causing the separation and movement of the chromatids. This process ensures that each daughter cell receives a complete set of chromosomes.

Interphase is the correct answer because it is the longest stage of the cell cycle where the cell prepares for division. During interphase, DNA replication occurs, resulting in the duplication of the genetic material. Additionally, proteins are synthesized during this stage, which are essential for various cellular processes. Therefore, interphase is the stage when DNA is duplicated and proteins are made, making it the correct answer.

During prophase, the nuclear membrane starts to break down, allowing the genetic material to be exposed. At the same time, spindle fibers begin to form, which will eventually help in separating the chromosomes during cell division. Therefore, prophase is the correct answer as it describes the phase where both the disappearance of the nuclear membrane and the formation of spindle fibers occur.
