Cell Division

What are the two main phases of the cell cycle?

• Interphase and Cytokinesis

• Prophase and Metaphase

• Interphase and Mitosis

• Karyokinesis and Cytokinesis

Which phase of the cell cycle is responsible for the duplication of genetic material and centrosomes?

• G1 Phase

• S Phase

• G2 Phase

• Prophase

Which of the following events occurs during Prophase?

• Chromosomes align at the equatorial plate.

• Sister chromatids separate and migrate to opposite poles.

• Chromatin condenses to form classical chromosome structures.

• The cytoplasm divides to form two daughter cells.

What is the most important change that occurs during Metaphase?

• Formation of two daughter nuclei.

• Chromosomes align at the equatorial plate.

• Disappearance of the nuclear membrane.

• Sister chromatids separate.

What is the primary event that characterizes Anaphase?

• Chromosomes decondense.

• The nuclear membrane reappears.

• Sister chromatids separate and migrate to opposite poles.

• The cell grows and enlarges.
