What happens during the G1 phase of the cell cycle?

• The cell grows and carries out normal functions.

• The cell enters a state of dormancy

• The cell divides into two daughter cells

• The cell begins to replicate its DNA

What is the purpose of the S phase of the cell cycle?

• DNA replication

• Protein synthesis

• Cell division

• Cell differentiation

What occurs during the G2 phase of the cell cycle?

• Cell differentiation

• Cell growth and protein synthesis

• DNA replication

• Preparation for cell division

In which phase of the cell cycle does DNA replication occur?

• G2 phase

• G1 phase

• S phase

• M phase

What is the first stage of mitosis?

• Telophase

• Metaphase

• Prophase

• Anaphase

What happens during prophase of mitosis?

• Chromatin decondenses into chromosomes, nuclear envelope forms, and mitotic spindle breaks down

• Chromatin disappears, nuclear envelope becomes thicker, and mitotic spindle stops forming

• Chromatin remains unchanged, nuclear envelope becomes stronger, and mitotic spindle disappears

• Chromatin condenses into chromosomes, nuclear envelope breaks down, and mitotic spindle begins to form

What is the role of the spindle fibers in mitosis?

• To provide energy for the cell

• To store genetic information

• To regulate cell growth

• To separate the chromosomes during mitosis

What is the significance of metaphase in mitosis?

• Chromosomes line up in the middle of the cell

• Chromosomes move to opposite ends of the cell

• The cell begins to divide

• The nuclear envelope breaks down
