1. In which stage of mitosis does the separation of sister chromatids occur?

Anaphase

Metaphase

Telophase

Prophase

During anaphase, the sister chromatids are pulled apart to opposite ends of the cell, ensuring that each daughter cell receives a complete set of chromosomes.

Explanation

During anaphase, the sister chromatids are pulled apart to opposite ends of the cell, ensuring that each daughter cell receives a complete set of chromosomes.

2. What stage of cell division is known as anaphase?

Telophase

Metaphase

Anaphase

Interphase

Anaphase is the stage of cell division where the chromosomes are split and pulled to opposite ends of the cell. Metaphase is when the chromosomes line up in the middle, telophase is when two new nuclei start to form, and interphase is the resting phase between cell divisions.

Explanation

Anaphase is the stage of cell division where the chromosomes are split and pulled to opposite ends of the cell. Metaphase is when the chromosomes line up in the middle, telophase is when two new nuclei start to form, and interphase is the resting phase between cell divisions.

3. During which stage of the cell cycle does DNA replication occur?

G2 phase

G1 phase

Interphase

M phase

DNA replication occurs during the S phase of the cell cycle, where the DNA is duplicated to prepare for cell division.

Explanation

DNA replication occurs during the S phase of the cell cycle, where the DNA is duplicated to prepare for cell division.

4. In which stage of the cell cycle does interphase occur?

Prophase

Metaphase

Interphase

Anaphase

Interphase is the stage of the cell cycle where the cell grows, carries out its normal functions, and prepares for division. It consists of G1, S, and G2 phases.

Explanation

Interphase is the stage of the cell cycle where the cell grows, carries out its normal functions, and prepares for division. It consists of G1, S, and G2 phases.

5. What stage of mitosis is characterized by condensation of the chromatin into chromosomes and the breakdown of the nuclear envelope?

Metaphase

Prophase

Anaphase

Telophase

Prophase is the first stage of mitosis where the chromatin condenses into chromosomes and the nuclear envelope breaks down.

Explanation

Prophase is the first stage of mitosis where the chromatin condenses into chromosomes and the nuclear envelope breaks down.

6. In the process of cell division, what stage is characterized by chromosomes condensing and becoming visible under a microscope?

Telophase

Prophase

Metaphase

Anaphase

Prophase is the initial stage of mitosis where chromosomes condense and become visible. Metaphase is characterized by chromosomes aligning in the center of the cell. Anaphase is when the sister chromatids separate and move towards opposite poles. Telophase is the stage where the nuclear envelope re-forms around the separated sister chromatids.

Explanation

Prophase is the initial stage of mitosis where chromosomes condense and become visible. Metaphase is characterized by chromosomes aligning in the center of the cell. Anaphase is when the sister chromatids separate and move towards opposite poles. Telophase is the stage where the nuclear envelope re-forms around the separated sister chromatids.

7. At which stage of cell division does telophase occur?

Telophase

Prophase

Metaphase

Anaphase

Telophase is the final stage of cell division before cytokinesis occurs. During telophase, the separated sister chromatids reach the opposite poles of the cell, the nuclear membrane starts to reform, and the chromosomes begin to decondense.

Explanation

Telophase is the final stage of cell division before cytokinesis occurs. During telophase, the separated sister chromatids reach the opposite poles of the cell, the nuclear membrane starts to reform, and the chromosomes begin to decondense.

8. In which stage of mitosis does the cell undergo cytokinesis and the chromatids decondense into chromatin?

Metaphase

Telophase

Anaphase

Prophase

Telophase is the final stage of mitosis where the chromosomes are at opposite poles of the cell, cytokinesis occurs to divide the cytoplasm, and the chromatids decondense into chromatin. Prophase is the initial stage where the chromosomes condense, metaphase is when the chromosomes align in the middle of the cell, and anaphase is when the chromatids are pulled apart towards opposite poles.

Explanation

Telophase is the final stage of mitosis where the chromosomes are at opposite poles of the cell, cytokinesis occurs to divide the cytoplasm, and the chromatids decondense into chromatin. Prophase is the initial stage where the chromosomes condense, metaphase is when the chromosomes align in the middle of the cell, and anaphase is when the chromatids are pulled apart towards opposite poles.

9. During what stage of cell division does the process of telophase cytokinesis occur?

Telophase cytokinesis

Prophase

Anaphase

Metaphase

Telophase cytokinesis is the last stage of cell division where the cytoplasm is divided and two daughter cells are formed. Prophase is the stage where chromosomes condense, metaphase is when they align in the middle, and anaphase is when the chromosomes are pulled apart towards opposite poles of the cell.

Explanation

Telophase cytokinesis is the last stage of cell division where the cytoplasm is divided and two daughter cells are formed. Prophase is the stage where chromosomes condense, metaphase is when they align in the middle, and anaphase is when the chromosomes are pulled apart towards opposite poles of the cell.
