Cell Division

What is the role of the G2 phase in the cell cycle?

• The cell prepares for mitosis by producing necessary proteins and organelles.

• The cell undergoes DNA replication.

• The cell divides into two daughter cells.

• The cell repairs any DNA damage before mitosis.

What is Mitosis?

• The process of cell division that results in two identical daughter cells.

• A type of cell division that produces four genetically different cells.

• The phase of the cell cycle where DNA is replicated.

• A process that occurs only in prokaryotic cells.

What happens during Interphase?

• The cell grows, duplicates its DNA, and prepares for division.

• The cell divides into two daughter cells.

• The cell undergoes apoptosis.

• The cell enters a dormant state.

What occurs during Metaphase?

• Chromosomes align at the cell's equatorial plane.

• Chromosomes are replicated in the nucleus.

• The cell membrane begins to pinch inwards.

• Spindle fibers are disassembled.

What is Anaphase?

• The phase where sister chromatids are pulled apart to opposite poles of the cell.

• The phase where chromosomes align at the cell's equator.

• The phase where the nuclear envelope re-forms around the separated chromosomes.

• The phase where DNA is replicated before cell division.

What is Cytokinesis?

• The process that follows mitosis, dividing the cytoplasm and organelles into two daughter cells.

• The phase of cell division where chromosomes are aligned at the cell's equator.

• The stage in the cell cycle where DNA is replicated before mitosis.

• The process of cell differentiation into specialized cell types.

What is the G1 phase of the cell cycle?

• The phase where the cell divides into two daughter cells.

• The phase where the cell grows and synthesizes proteins.

• The phase where DNA is replicated.

• The phase where the cell prepares for mitosis.

Why is DNA replication important?

• It ensures that each daughter cell receives an identical set of chromosomes.

• It allows for genetic variation among offspring.

• It helps in the repair of damaged DNA.

• It facilitates the process of protein synthesis.

What occurs during the S phase of the cell cycle?

• DNA replication.

• Cell division.

• Protein synthesis.

• Chromosome condensation.

What happens during Prophase?

• Chromatin condenses into chromosomes, and the nuclear envelope begins to break down.

• The DNA is replicated, resulting in two identical sister chromatids.

• The spindle fibers begin to form and attach to the centromeres.

• The cell membrane starts to pinch inwards, preparing for cytokinesis.
